BCD China mainstream in the field of power supply IC manufacturers, hangzhou silan, CRC silicon micro, wuxi core friends, shenzhen core group, and into the microelectronics, Beijing prosperous shimmering, semiconductor, etc., and found that these companies are full of confidence, "and says it has become the main source in many power supply IC.
"China IC manufacturers have, in fact, in the small power AC/DC and DC/DC power supply, various linear voltage regulator, voltage reference, all kinds of LED drive, battery management, battery monitoring, lithium ion battery management, protect consumer electronics applications such as edge. The prices of Chinese IC manufacturers are lower, mainly due to the same performance indicators. "We pay more attention to the early system design work, and solve the higher cost performance of IC design from the system optimization," said sheng jun, sales director of the company. The products of our company and international power IC manufacturer PIN TO PIN are L6562D, IR2520D, ZXLD1360, etc.
However, wu xin, senior director of BCD products, thinks that besides the price, the performance of domestic IC is also surpassing the competitors. "local manufacturers have gained a great advantage in linear regulators and benchmark voltage. Whether in product price or product performance and reliability. For example, BCD has strong competitiveness in the field of chargers control chip, LED lighting driver chip, LED backlight control chip, etc., and even surpass the international factory.
Advantage for Chinese manufacturers, Beijing electronic technology company CEO pei spirifer whang explains - in consumer electronics, home design company has increased more for the battery and related applications of chips, one reason is that China is the world's consumer electronics major production base, most of them are made by the lithium battery power supply, it will need more and more intelligent lithium battery discharge management chip. So for these applications, local design companies have invented and designed some new lithium battery intelligent management chips to meet these market needs. For example, a unique chip called SE9120, "we defined and designed SE9120 from scratch in the lab. This is the only single chip solution that can measure battery power and display battery power on LCD and LED. It has just entered the market and sold 10 million units in six months.
Interview, everyone agreed that the current Chinese manufacturers are still in a weak product areas mainly integrated power solutions, power MOSFET, application processor of the integrated power management, hot-swappable power management, digital power control solutions, high voltage power supply and other industrial applications. "It is mainly due to the lag of domestic production process and system design experience in terms of reliability and other indicators." Shengjun analysis.
Power supply such as mathematics, CRC, deputy general manager of silicon micro marketing Fang Guoteng explains, digital power technology for large power system, the effect of energy saving can play concrete and digital power supply current uniform interface PMBus supplier, also more and more, but the domestic IC manufacturers into concerned, should be limited. He is not personally particularly recommended. But he also believes the huge potential of digital power supply are revealed: "originally digital power control for the power density of the contribution is still in dispute, but the advent of cloud computing impetus to the development of container type server, demand is very heavy, the demand for digital power control technologies quickly established the irreplaceable position of digital power."
Another weak area for Chinese manufacturers is the integrated circuit module. "Integrated power solutions should be Chinese suppliers for weaknesses, because it requires a large investment, and the main chip system closely, due to the current domestic main chip system is weak, the supporting company cannot fully engaged." Li zhihong of wuxi xinpeng microelectronics co., LTD.
However, wu jianxing, general manager of the power supply and power drive product line of hangzhou shilan microelectronics co., LTD., thinks that in MOSFET and integrated power module market, there is a breakthrough in the microelectronics of shilan. "Discrete device manufacturers in China has made significant progress, has been able to mass production and planar slot type grid power MOSFET, in the low-end applications has occupied a considerable market share." He said. However, he also acknowledged that "international brands such as Europe, the United States and Japan, with long-term technical accumulation and parameter performance advantages and quality reputation, still occupy an absolute leading position in high-end products." He explained, high-voltage power MOSFET worthy of attention in recent years is a development trend of the Super JuncTIon (Super JuncTIon) structure of the application of high voltage MOSFET in speed up and popularization, the technical indicators are in constant progress, and domestic manufacturers have not production products. "The research and development of Super JuncTIon structure technology has been carried out in shilan microelectronics." He said.
In addition to the above hot spots, the Chinese manufacturers have focused on tackling and achieving important successes, including LED drivers. The following will be discussed on AC/DC and DC/DC power supply, LED drive, and integrated power module.
