Traditionally, to be an adapter and to be a power control module, these technologies have become too mature. Power engineers have worked hard and passed certifications, but only a meagre profit. Obviously, the power management IC itself and the power system engineers have been deducing the energy conservation and environmental protection trend to the limit. Taking into account the maturity of the power IC technology, power semiconductor companies want to be successful, achieve differentiation and enhance the added value of the "treasure." Began to pressure on the specific application industry.
Looking forward to 2011, power semiconductor manufacturers want to gain more, and tapping into emerging industries to dig out hot applications is a great way to increase the added value of the power industry. This article will explore several areas that have attracted attention and will continue to generate hotspot effects.
Hotspot 1: Opportunities in the Commercialization of Electric Vehicles With the support of policies, the commercialization of electric vehicles is witnessing faster and faster. Electric vehicles (or hybrids) and electric bicycles have gradually become the mainstay of new energy vehicles. Applications such as powertrain control systems, motors and drive systems, and battery management systems have become a hot topic for semiconductor manufacturers in recent years, and many ICs have been created for this area.
In many electronic devices, the power supply is only an auxiliary component, and “electrical†in electric vehicles has become a core component. The power system design engineer plays a central role in this application. Here, the battery management system is closely integrated with the power battery of electric vehicles (including electric vehicles, electric bicycles, and electric motorcycles, etc.) to detect the voltage, current, and temperature of the battery at the same time, and also to perform electric leakage detection and thermal management. , battery balance management, and give full play to battery capacity. Popular products in this area include Linear Technology's battery pack monitor LTC6802 that can measure up to 12 stacked battery voltages, Atmel's lithium-ion battery management chipset ATA6870/71, and O2 Micro's support for on-demand equalization (BOD) technology The electric vehicle battery management chip OZ8902 and so on.
O 2 technology is to launch a complete MG110 solution for electric vehicle powertrain systems, including smart battery management system MGB110, smart car charger MGC110, and smart car DC/DC converter MGD110 and other three products. In addition, more cutting-edge technology is that Infineon’s newly established Beijing Automotive R&D Center has been developing radio-coupled charging.
IGBT chips for automobiles have always been high-tech devices. Traditionally, international semiconductor manufacturers have occupied leading positions in this field, such as Infineon, International Rectifier (IR), Vishay, etc. For example, Infineon introduced the HybridPACK series for electric vehicles. IGBT modules, IR use 1200V IGBT for welding metal (SFM)? AUIRG7CH80K6B-M. But the good news is that BYD Microelectronics, a local manufacturer, has also launched a 1200V IGBT chip with its own R&D die.
Hotspot 2: New energy applications swell Moore's law with a rapid increase in speed. The semiconductor industry does not seem to have confirmed, but the growth rate of the solar market is expected to catch up with Moore's Law. Market research company iSuppli points out that photovoltaic (PV) module-level power management Global shipments of (MLPM) systems will erupt in a few years, and it is expected that by 2014, MLPM overall shipments are expected to reach 7.8 GW. Now, the development of the solar photovoltaic industry has come a long way, and it has entered the stage of seeking to improve performance and reduce costs. ICs for solar energy applications have been innovative in terms of efficiency, reliability, and stability.
According to iSuppli's report, global solar inverter shipments are expected to exceed 23.3 million units in 2014, which is 9 times the 2.6 million in 2010, while the average price per watt has dropped by 13.5% globally. In the field of inverters, mature technologies have made inverter conversion efficiency of more than 90% for many semiconductor manufacturers (not only TI, Fairchild, ON Semiconductor, Infineon, etc., but also many domestic power supply manufacturers). Due to the remote and harsh working environment of most independent solar power generation equipment, it is an inevitable trend for the inverter to add circuit short-circuit protection, under-voltage protection, over-current protection, reverse connection protection, and lightning protection.
In addition, special-purpose special-purpose ICs are gradually emerging to help achieve higher conversion efficiency or enhance the performance of inverter power supplies. For example, SolarMagic chipsets for photovoltaic panels, which are introduced by National Semiconductor, are used to monitor inverses. An integrated solution to convert power supply voltage and current to the AS8002; NXP Semiconductors provides MPT612 for low-power integrated circuits that provide maximum power point tracking (MPPT) for applications that use solar photovoltaic cells or fuel cells.
Hotspot 3: LED backlighting applications In LED backlighting applications, even large-screen displays and TVs typically consume hundreds of milliamps. Therefore, compared to high-power lighting applications, consumer electronics are used in LED backlighting. The drivers are more mature in terms of technology, products, and markets. At present, mainstream TV makers have even adjusted the proportion of LED-backlit LCD TVs to 30% to 50%, which has led to fiercer competition in this area.
The maturity of the technology is reflected in the fact that the efficiency, reliability, etc. of such drives are all approaching the limit. At present, the peak efficiency of LED drivers for mobile phones, gaming devices, MP3 players, notebooks, netbooks, and tablet PCs and other small LED display-backed applications is generally over 90%. Manufacturers active in this field include Fairchild. , Maxim, Infineon, Onsom and other companies.
In addition, more and more company-launched LED drivers have their own unique performance. For example, some LED drivers have precise dimming capabilities, including Intersil? ISL97671/2/3/4 can control the matching current between LED strings to ±0.7%; dot matrix LED drivers are becoming more miniaturized, such as Austria Microelectronics can drive 144 LEDs AS1119 footprint is only 9 Mm2.
Hotspot Four: High-power LED Lighting Demand Enhancement Although the current LED lighting application market has not made much progress, and the industry’s views on “whether or not LED should be made into bulbs and street lamps†have been divided, but such differences have not completely stopped The development of high-power LED technology, and the Chinese government in recent years to vigorously develop the LED industry, is also a large number of bidding LED lights and energy-saving lamps and other lighting products, but also through the financial subsidies to promote the development of LED chip companies, official support and green The demand makes LED lighting still occupy the attention of the market.
Although the Chinese LED market is supported by the Chinese government, compared with the United States and Taiwan, China's LED manufacturers are lagging behind in terms of technological capabilities. According to iSuppli's report, China also lacks core and upstream intellectual property (IP), such as MOCVD equipment and LED wafers. In general, LED has to enter the general lighting market, and there is still room for improvement in materials, light efficiency and reliability.
However, the technology for semiconductor driving applied to LED lighting is very mature. Some AC/DC lighting driver chips can achieve current accuracy of +/- 1%, and more and more functions are integrated, such as Cypress. Semiconductor company's AC/DC digital power controller CY8CLEDAC01/02 for LED lighting can perform automatic dimming detection, so it can be used with existing mainstream wall dimmers, and can be reduced to 2% without flicker;锜Technology Needle input voltage 16V ~ 400V and PF value greater than 0.9 of the LED lighting drive program RT8458.
There is also a demand for high current LED drivers in consumer electronics, such as camera phone flashes. The austriamicrosystems white LED flash driver AS3645 inductive flash driver can drive up to 1,000mA; National Semiconductor's LM3554 can use a lithium battery to drive loads up to 1.2A. For camera flashes, ON Semiconductor's ultracapacitor-based LED drivers, the NCP5680 and CAT3224, provide high flash currents of 10A and 4A, respectively.
In the automotive industry, LED lamps are also becoming more and more popular. Such applications generally require higher voltage step-down LED driver ICs. Currently, there are many new LED drivers that can withstand 60V high voltage, and many companies have introduced dedicated driver control for high-brightness LEDs. Chips, manufacturers of these LED driver ICs include Melexis, Infineon, Linear Technology, ADI, China Resources, and others. Linear Technology's LT3496 can drive up to 24 500mA LEDs with up to 96% efficiency; NXP Automotive LED Drivers ASL1010NTK and ASL1010PHN integrate many core functions such as direct LED temperature feedback, LED fault detection, internal pulse width Dimming control, short circuit protection and other functions).
The constant current technology designed to meet the different needs of LED backlighting, LED high-power lighting, LED lights and other specialized fields, pulse width modulation integration technology integrating brightness adjustment, high-voltage technology and ultra-high brightness high current technology, etc. It will be an important research direction for LED driver IC manufacturers in the coming year.
Looking forward to 2011, power semiconductor manufacturers want to gain more, and tapping into emerging industries to dig out hot applications is a great way to increase the added value of the power industry.
