Right at the beginning of 2010, the semiconductor giant Intel sent in addition to a new processor and chipset series for the desktop segment, a new generation of notebook components, which should make the new technologies available for the move.

For "Caramel", "Sonoma", "Napa" and "Montevina" is the name of "Calpella" baptized platform - with the exception of the two variants of Napa Refresh and Montevina - already the fifth generation of Intel’s Centrino platform known that Since 2003, more than any other brand in the notebook segment is traded. The Intel Centrino mobile technology represents the combination of Intel mobile processor, Intel mobile chipset and a wireless LAN module out of that house. Beginning with the Pentium M series on the Core Duo / Solo processors up to Core 2-generation Intel has been steadily developing the platform. The new ‘Calpella’ platform now relies on processors from the respective mobile Core i7 series (high end)), i5 (Mid-range) and i3 (Mid-Range/Low-End. The three top models from the Core i7 series, which were approximately four months prior to the start, be extended to the present day by no less than ten smaller siblings.

The new processors based on the "Arrandale" core all have two processing cores with Hyper-Threading feature. With the exception of the Core i3 Series also may use all CPUs on the familiar turbo mode, which in the case of the Core i7-620, the clock frequency depending on the utilization of 1.06 to 2.13 GHz smooth doubled. The clock of the integrated graphics unit is directed primarily towards the underlying thermal design power. Thus, the GPU clock rate of the models with 18 or 25 watts TDP, with a maximum of 500 MHz, in the models with 35 watt TDP, the maximum frequency ranges of 766 MHz range, which is considerably higher even than the popular models like the desktop spin, which integrated graphics unit - except controlled from the core i5 661 - with only 733 MHz. An additional feature also arises from the fact that the mobile can spin the turbo mode function not only apply to the CPU, but also on the GPU. If the CPU load at a high utilization of the GPU comparatively few, the clock speed of the GPU dynamically controlled upwards, provided that the maximum TDP is not exceeded.

Also in the chipsets is heating up. Besides the well-known PM55 Intel expands its portfolio equal to five other models are derived primarily from their offshoots from the desktop segment, which is why the functionality is similar to the utmost. For a little confusion with the new Intel makes HM57 chipset, which has, depending on the size of the firmware images have different characteristics. While in an eight megabytes large image of the chipset has a feature for remote maintenance and protection of identity holds, those with a firmware with only four MB capacity. Willing buyers must therefore pay attention not only to the pure chipset, but also on the size of the firmware images, provided the two additional functions are urgently needed. The difference between the QM57 and QS57 is, however, only the form factor, the functions remain the same. Apart from the entry-level model HM55 all offer a total of 14 USB 2.0 and six serial ATA II ports, eight PCI Express x1 lanes, and four PCI device. With twelve USB 2.0, four Serial ATA II, and six PCIe x1 but should not be an HM55 for most tasks in a notebook more than adequately equipped.

As the successor to the Intel WiFi Link 5000-series have in the future three or four models of the new Intel Centrino 6000 series, the challenge of combining the respective laptop wirelessly with the outside world. This Intel relies not only on the current wireless LAN standard i802.11n, but continue on WiMax, the technology will also transfer over long distances in the broadband sector returns, so far, at least in Germany, rather less use. The new top-Intel Centrino Ultimate-N enters 6300, the successor to the Intel WiFi Link 5300 and has as its predecessor, the maximum gross transfer rate of 450 Mbit / s. The next smaller model Intel Centrino Advanced-N 6200 is replacing the WiFi Link 5100 and doubles the bandwidth over the predecessor of 150 to 300 Mbit / s. For the boarding area, the Intel Centrino 1000 module is available, which nevertheless still 150 Mbit / s provides. The variant Intel Centrino advanced N + 6250 WiMAX alongside the i802.11n standard also supports multi-band WiMAX in the frequency ranges 2.3, 2.5 and 3.5 GHz and is thus used worldwide, according to Intel. The peak throughput is at least 20 Mbit / s downstream.

Intel currently has in the portable computer market share from currently 88 percent, while direct competition with the name of AMD, only 11.9 percent of the market can claim for themselves. Face of the new product offensive, at least in the near future, no turnaround in sight, especially since Intel this year with a combination of CPU and GPU has a small package on a unique selling point, unless AMD can surprise with an early launch of the Fusion Technology .

EU report pushing hydrogen fuel to reduce fuel consumption and traffic: dell inspiron 8600 battery , dell inspiron 8600m battery , dell inspiron 9300 battery , dell inspiron 9400 battery , dell vostro 1000 battery , dell vostro 1400 battery , etc.

Russell February 25 (Xinhua Fang) The European Commission released a report on the 25th shows that if from now on to vigorously promote the hydrogen fuel, then by 2050, the EU road transport fuel consumption is expected to less than the current 40 %.

Report said, whether it is from the environment or from an economic point of view, the use of hydrogen fuel for sustainable development in the transport sector are the most viable option.

However, this study funded by the European Union also noted that the promotion of hydrogen fuel currently still faces economic, technological and institutional series of bottlenecks. On the one hand, the EU faced with good opportunities are likely to take the lead in the development of hydrogen fuel and fuel cell technology, be used for transportation and energy supplies. On the other hand, very severe challenges, the EU must take the right move as quickly as possible.

The report holds that the EU needs to significantly reduce the cost of hydrogen fuel terminal applications, particularly in the transport sector the cost of application of hydrogen fuel, in order to make hydrogen fuel more competitive.

The report estimates that if the hydrogen fuel in a smooth, from now to 2025 to 2035, the European Union to promote the benefits of hydrogen fuel would be sufficient to compensate for pre-investment, in 2030, the EU will have 16 million vehicles use hydrogen fuel, and hydrogen fuel-related infrastructure construction investment will total 600 million euros.

Report argues that if the hydrogen fuel technology has the world's leading-edge, the EU will be able to win new economic opportunities, enhance their competitiveness.

Recent trends show that color is rapidly becoming the majority of new mobile phone, PDA and digital camera standard. Color screen, games, Internet browsing and messaging features required by the use of more and more time display, how to effectively support the needs in this area as the power-management device manufacturers focused on "care" object. ON Semiconductor's analog portable and consumer product applications director Bernie Weir, said: "In 2003 the number of mobile phone replacement for the first time than the whole 50% of the total mobile handset sales, these second-and third-generation mobile phone users have a wealth of mobile phone use experience, want the phone to become a color LCD with multi-media voice communications hardware | tools. how we can effectively support the mobile phone color display, Internet browsing, games and send text messages and other functions, in order to increase the time used in LED backlighting is a designer to give priority to One of the major micro-watts of power for each must be careful planning. "

Increasingly high-definition display, the screen shining bright color even more than before, which makes increasing the power consumption of displays, how energy efficiency has become the portable equipment designers need to face a major problem. For energy-saving improvements made to involve almost every corner of the display system. NS company's Asia Pacific marketing manager, display products Chen Yongxin introduced a new technology - Mobile Pixel Link (MPL), which is the baseband processor and the screen / camera between an interface can be connected together on chip to reduce the hinged bit line, thereby reducing the energy of these lines and the consequent loss of electromagnetic interference.

In addition, to provide backlighting for the display of the luminous body is the system power consumption among the largest circuit, its power consumption is the display received more than ten times. Fairchild's technical marketing engineer Enrique Rodriguez said, "in a variety of LCD display backlight programs, LED method by reducing the number of external components such as converters, etc., which can significantly reduce power consumption. In addition, a variety of LED Driver Program are using pulse width modulation (PWM) to reduce the average LED current, thus reducing the power required to drive the circuit. "

At present, manufacturers are developing more advanced LED charge pump products that enhance the backlight power. "The market demands the current LED charge pump device to the main screen, sub-screen display and at least one RGB display backlight power." Linear's Armstrong said. He noted the design requirements of the ever-expanding product features, "Current accuracy and brightness matching problem is very complicated, although the engineers for the 10% of the current accuracy still capable of acceptance, but they can not match the precision of zero tolerance for more than 5%."

Another place could be further savings in electricity is the camera's preview of the system. Under the current design, even in the preview stage, all image data have to be first sent to a controller, and then returns the display. Transfer data back and forth so completely unnecessary waste of energy because after the image data in the preview will all be deleted. NS newly introduced LCD driver can support a wide video bandwidth, and built-in 2D scaler, so the camera can function in the implementation of preview to establish contacts directly with the display module in order to transfer data. The design is to ensure the camera preview function in the implementation, the baseband processor and the hinged bit can be completely idle, help to further save energy.

Switching devices to eliminate electromagnetic interference with the win-win situation

In many portable applications, the switching regulator is being replaced by a linear regulator to extend the battery run-time, but the noise and electromagnetic interference (EMI) problems followed. However, many portable devices have a radio circuit and RF receiver, they are very sensitive to noise. Therefore, as a noise generator, switching power supply, is bound to these sensitive circuits is a potential interference. The most common solution is twofold: one to improve circuit design, and second, additional shielding. The traditional solution is to make the noise happen far away from the circuit for noise-sensitive circuitry. However, in today's portable products (such as smart phones), because of the internal layout of the system very closely, this approach is no longer feasible; while additional programs will be shielded because of the cost and size constraints, have become impractical .

Fairchild's Rodriguez said: "The current trend is to use spread-spectrum technology to reduce the EMI of the power of the signal components. In the regulator to use different frequencies can reduce the power components, thereby reducing the amount of EMI." The company's FAN5602 it belongs to a products, it is a common switched-capacitor DC / DC converter that can adjust the resistance values in order to control from the input switch to rapidly charge capacitor amount. This modulation can be the device to minimize peak current, the final and reduce EMI. Luo Zhenhui half the country believes that the efficiency of switched-capacitor regulator continues to improve its practical efficiency and magnetic switching regulators or less, which is to solve electromagnetic interference is a feasible option.

Linear's Armstrong also said that a practical noise reduction technology is to enable DC / DC converters generate high-frequency jitter system clock. This approach coupled with spread-spectrum operation, can take advantage of a pseudo-random number (PRN) sequence of pairs of switching frequency modulation, in order to eliminate narrow-band harmonics. According to him, the company's LTC3251 is realized with a chip on-chip spread-spectrum example. LTC3251 is a 500mA, high efficiency, low noise and no inductor-based step-down DC / DC converters, the spread spectrum oscillator is designed to generate a case-cycle time interval between the random (but fixed 1MHz and 1.6MHz between) the clock pulse and design. This has the advantage of switching noise can be scattered over a large number of frequencies.

In portable applications, a variety of device integration is inevitable. As the Taiwan power management chip maker RichTek Technology said: "The future space-based needs of small and high-efficiency, integration is imperative." Multi-input, multi-function devices are starting to charge, control and management functions rolled into one. Power controller and power management chips (traditionally are interrelated but independent of each other) is an integrated chip with a number of the charger feature integrated. National Semiconductor's Luozhen Hui said: "We knew this market trend, such as the application processor on the market not only have the required pre-loaded software, but also to gradually more other hardware, such as man-machine interface, machine interface, built-in in the processor. "According to him, the company has been working closely with the application processor vendors committed to provide the market with a highly integrated solution to meet a variety of load requirements.

Fairchild's Rodriguez also pointed out that the design community there is a latest trend is the introduction of these power management unit to the application processor for further power optimization in the future. He said: "To achieve this goal must be to overcome a number of challenges, including the development of an active development plan and to address the increase in cost and power of the thermal characteristics of the problem."

"We're currently offers fully integrated with a battery management capabilities, multi-input, multi-function power management devices." TI's Heyer said, "In addition, the size of the larger power management chip to effectively meet the critical system power demand, market opportunities and increase in quantity and design. For example, power supply with 10 or more channels of devices commonly used in specific designs, such as smart phones or digital cameras. However, the Asian market for smaller sizes, 1 to 3-channel devices, the demand for larger, a linear regulator, such as the integration of DC / DC switching regulator. We think that this demand will continue to exist, because these devices to avoid excessive integration, suitable for different types of applications. "

Portable products require more advanced power management and battery management in order to minimize power consumption, and energy calculations to find the remaining available energy, or the system when they can once again put into operation methods to optimize the system performance and uptime. In order to get the best price, the new battery-management chip in a single-chip package device integrates all of the battery-management functions. Microchip's battery management products vice president Jim Vernon said: "The charge control, power monitoring and security features for the measurement of temperature, voltage and current demand for a common, single-chip solution eliminates the duplication of functions in the system. This single-chip solution that can provide more benefits, since each feature is independent and can be achieved at the system level battery management, rather than a single component to achieve. "

In addition, there is a trend is the use of USB battery charging for portable devices, portable devices commonly used in lithium-ion batteries will be using this technology. Fairchild's Rodriguez said: "USB 2.0 specification provides for two completely different power classification (high and low), voltage nominal value is 5V, while the surge current to allow the value compared to 500mA. That the data in USB function outside the integrated battery charging function of ability to extend battery life in devices. "

Linear recently unveiled a LTC3455, can meet the standard of USB power under the AC adapter, USB cable and power between the lithium-ion batteries for seamless mobility. The device integrates a fully functional lithium-ion battery charger and two high efficiency synchronous buck converter, the former can provide up to 800mA charge current, which is used to generate the majority of USB peripherals required for low-voltage rail. LTC3455 also provides for microprocessor power-on reset signal, used to supply hot-swappable memory card output, as well as suitable for low-battery comparator or LDO controller gain spare parts.

For portable applications power | Regulators management is becoming the field of eye-catching highlight of the semiconductor. According to market research firm CIR report released by the market the next few years, the power supply devices for portable applications based on the market prospects are very positive.

Portable devices growing number of new features, power management will be the formation of a large number of new demands. At the same time, portable device manufacturers are facing increasing pressure, they must integrate these features into ever-shrinking in size, the same time it maintained a long working hours.

For example, with the advent of 3G, mobile phones not only to browse the Web, send e-mail, take digital photos, or even to be able to play the video stream, which will bring enormous challenges in power management. Meanwhile, with the acceleration of processor speed, the entire power management program and the various sub-systems must keep pace with this change, providing support for supporting the power. In addition, the new battery technologies, especially micro fuel cell technology commercialization is about to begin, forcing chip makers to rethink the future of the power supply system design.

Correspondingly, these new trends but also the power to create tremendous business opportunities for chip makers, prompting them racked their brains to develop more advanced, with different features and sizes getting smaller and smaller power management solutions to support the increasingly complex system power requirements and new features. To fully understand the depth of today's portable power management applications on the latest trends, this paper specially invited a leading semiconductor company Texas Instruments | Instruments (TI), Fairchild (Fairchild), Linear (Linear), ON Semiconductor, National Semiconductor (NS), Microchip Technology (Microchip) and RichTek Technology to share their insights and wisdom.

Power management device package, to strike a balance between efficiency and cost

In the terminal equipment of the small size trend, the systems engineer required to power the device must be able to extend battery life and reduce circuit board area. Suppliers in the design of these devices, you need efficiency, package size and cost trade-off between the repeated. Fairchild Semiconductor's Asia Pacific president, Kuo said: "The small package size of the cooling capacity of less than large-size packages, forcing us to improve the efficiency of power conversion devices."

Microchip's Analog and Interface Products Division, senior marketing manager George Paparrizos pointed out that the system design, power depends on the input / output voltage and the difference between the required load current. "As the new digital devices require larger currents, the two main ways to reduce energy consumption only slightly higher than the input voltage for the introduction of the output voltage, or take intelligent control system." He said that the higher power requirements, stimulus that can save space and have a higher thermal performance, a new packaging technology development, but also so that no-lead package (DFN and QFN) popular.

Voltage conversion in portable applications is also increasing the number, it was considered necessary for power conversion using the same high-density packaging. TI Portable Power Management Global Business Marketing Manager Patrick Heyer, said: "The improved packaging technology will continue to work to reduce the footprint area, close to the size of the internal silicon, providing a good thermal conductivity, lower costs and meet the standards of customer processing requirements. More chip packaging technology will be allowed to provide more comprehensive functionality, while minimizing external component count. "

He also pointed out that the wire (Bond wires) will continue to give the solder bump, or other innovative technologies that allow the power chip can withstand high current, high fever and high-frequency signals. Innovative circuit design, performance will be used to create the conditions to improve the characteristics of these features include soft-switching, optimized gate driver, higher precision, higher switching frequency and better control algorithms.

Most of today's portable devices are present in a variety of charging power supply, in order to narrow the circuit board space to achieve the best efficiency and power management for battery design becomes increasingly complex. Linear's Power Business Unit product marketing manager, Tony Armstrong, said: "Just look at such as digital cameras, MP3 players, GPS receivers and PDA, etc. can be at a glance. Most of these products by the AC adapter, USB interface or a lithium-ion battery-powered. The power supply between the access control is a major challenge. "

He went on to say, engineers have been trying to use discrete components to achieve the above functionality, but it faces great difficulties, such as hot-swappable and can cause serious system problems of surge current. Most battery-powered portable products use a dedicated power supply chips to achieve the battery charging, power of access control, providing multiple supply voltages, and as a true output disconnect and accurate USB current limit such protection. The reasons for adopting this approach is very clear, that only a single device can satisfy all of its power management requirements. However, doing so also has shortcomings, dedicated power supply chips, congenitally deficient lead to very difficult for all the above functions to achieve maximum performance, and made the transition from product design to production time becomes very long.

The field of power management for the future development trend, the National semi-Asia-Pacific portable device power management product marketing manager for Luo Zhenhui that the future power management system should not only focus on the switching regulator of the conversion efficiency, should also carefully consider whether the power management chip stability in bulk supply as well as the package is small, and even a very small package, the chip power consumption, accuracy and noise levels should not be subject to the slightest impact.

Mobile phone flash created a new demand

Camera phones and other functions in the emergence and continued deepening of the power management of a more serious challenge, because these new features are basically belong to the "energy-hungry" applications. For example, consumers want to be able to capture higher resolution camera phone pictures, and can indoors or in dim ambient light conditions to shoot. These requirements compel designers to start thinking about in the phone configuration flash functions, while the white light led to become the preferred flash light.

For handset design engineers, the white LED has a variety of features they need: small form factor, high-brightness output and to provide flash and continuous video capability lighting, LED vendors have developed specifically for mobile phone flash of high output power LED. However, these high-brightness LED While it is suitable for lighting purposes, but they are also big battery power.

"Although the use of high-power LED to form a visible light of this basic task is simple, but if we do not improve the existing design, it is difficult to build high-performance power supply and current control programs." Linear's Armstrong said. According to him, Linear's LTC3453 is a designed to optimize the efficiency, accuracy and LED current control products designed to examples, suitable for high-current camera flash applications. The product uses synchronous buck - boost-type power architecture and programmable low dropout current sources to regulate LED current.

Buywhere: sony VGP-BPS14 , sony VGP-BPS14/B , sony VGP-BPL14 , sony VGP-BPL14/B , sony VGP-BPS15 .

The device according to VIN and LED forward voltage synchronous buck, synchronous boost and four-switch buck - boost mode automatically transform between. Each current source has its own independent control loop, and can at a very low LEDx pin voltage regulator under the conditions of current, designed to minimize power consumption. With the synchronous buck - boost topology, "flashlight" mode efficiency up to 90% more than the standard step-up compared to alternative solutions to enhance a rate of 20 ~ 30%.

Fairchild Semiconductor, introduced a highly efficient LED flash driver FMS2000 and FMS2004. Alleged that these devices can flash intensity / duration, reduce red-eye reduction, movie mode, white balance, and the battery voltage compensation features programmable control.

In addition, Microchip's Security, Microcontroller and Technology Division product marketing manager, Fanie Duvenhage also said that flash microcontroller will also play an important role in the solution. He said: "People want to be able to adapt to different flash brightness level to a different order of the flash, and display a different color. This can not be stand-alone power conversion chip, but rather the need for additional programmable microcontroller. However, many Designers do not want to be outside the micro-controller for a power conversion device pays for, so power conversion functions are often included in micro-controller being. "
