Opportunity is often the opponent's mistake and make mistakes, but we must fully prepared. In march this year a Japan earthquake and subsequent nuclear leak and power brownouts, making the Japanese and the European and American some semiconductor manufacturers influence production, including power supply IC is affected large device, which makes Chinese engineers and purchasing masters will be looking for local second source as an important task to complete, and probably, the second source after the full verification in the future, will become the main source of supply. Although not the opponent's mistake, but the chance is coming, China power supply IC manufacturers, you ready?

This newspaper about the topic interviewed China power supply IC field of mainstream manufacturers BCD, hangzhou, China resources ShiLan silicon micro, wuxi core friends, shenzhen core group, and into microelectronics, Beijing think prosperous and can red semiconductor, etc., found that these manufacturers are full of confidence, and said in a lot of power IC has become the main source of supply.

"In fact, the Chinese IC manufacturers have in small power AC/DC and DC/DC power supply, all kinds of linear regulator, voltage reference, all kinds of LED driver, battery management, the battery power monitoring, battery charging management, lithium ion protection consumer electronics applications have the upper hand. Mainly displays in the performance of the same Chinese IC manufacturers price lower. Core union semiconductor sales director ChengJun said. "technology, we pay more attention TO the system design work, from the system optimization TO solve the late IC design higher price. Our company and international power IC manufacturers PIN TO PIN products have L6562D, IR2520D, ZXLD1360 etc."

And BCD products senior director WuXin argues that in addition to the price, domestic IC performance are also beyond the opponent, "local firms in linear regulator, voltage reference has a greater advantage. Both in the price of the product and the product performance and reliability. Such as BCD in charger control chip, LED lighting driver chip, LED backlight control chip etc products have strong competitiveness, rival even more than the international leaders."

Chinese manufacturers to the advantage of Beijing think popular electronic technology company CEO pei spirifer explain, in consumer electronics, local design companies increased more according to the battery and related application of chip products, one of the reasons is that China is the world's consumer electronics of the main production base, most of them by the lithium battery power supply, this natural will need more and more intelligent lithium battery discharge management chip. So according to these applications, the local design company invented and design some new lithium battery intelligent management chip to meet the market demand. For example, think flourishing a unique chip is SE9120, "we in the laboratory from scratch the definition and design the SE9120. This is the world's only one can measure the battery power and can be displayed on the LCD and LED the battery capacity single chip solutions, its just six months into the market to sell ten million star."

The interview, you agree that at present Chinese manufacturers is at a weak products field is mainly integrated power solutions, power MOSFET, application processor integrated power management, hot plug power management, digital control power solutions, high voltage power supply, and other industrial applications. "Is mainly due to the domestic production technology and system design experience behind cause the reliability indicator of behind. ChengJun analysis.

Such as mathematics power, China resources silicon micro market sales deputy general manager FangGuoTeng accounts, digital power supply technology for high power system energy saving can specific play effect, and digital power supply currently unified interface PMBus suppliers, more and more, but the domestic IC manufacturers in this attention, should be very limited. His personal now also don't particularly recommended. But he also thought that the great potential of digital power is revealed: "originally digital power control for the power density of the contribution is still in dispute, but the arrival of cloud computing drive container type server development, the demand is very fierce, the digital power control technology needs immediately established digital power do not replace position."

Chinese manufacturers another weak areas are integrated circuit module. "Integrated type power supply solution should be Chinese manufacturers now weaknesses, because it needs large investment, and the main chip system closely, due to the current domestic main chip system also is weak, the company cannot form a complete set to input." Wuxi core friends microelectronics co., LTD. LiZhiHong.

However, hangzhou ShiLan microelectronics co., LTD., power supply and power drive product line WuJianXing think, general manager of the MOSFET and integrated power module market, ShiLan microelectronics has a breakthrough. "China's discrete device manufacturer has made significant progress, have been able to mass production planar and slot gate type power MOSFET, in ZhongDiDuan applications already occupy a large share of the market." He says. But he also admitted that "Europe, America, Japan and other international brand companies with long-term technical accumulation and parameter performance advantages and quality reputation, in the high-end product still occupy absolute leading position." He explained, high voltage power MOSFET is worth to pay close attention to in recent years as a development trend is Super Junction (Super Junction) structure of the application of high voltage MOSFET in accelerating and popularization, the technical indicators in constant progress, and domestic manufacturers are no production product. "ShiLan microelectronics has begun to Super Junction structure technology research and development. He revealed.

In addition to the above hot outside, Chinese manufacturers more concentrated research and made a big success include LED drive field. The following on the AC/DC and DC/DC power supply, LED driver, and integrated power module several fields are discussed.
