Products with high voltage and high current, high reliability, high efficiency, low standby, high power density and other characteristics, has a high price and strong market competitiveness. To meet customers better complete program development, Silan has specialized application technology team to provide system solutions support, especially small household appliance market will go "turn key" mode. In addition, Silan also invested one million U.S. dollars to build, "EMC achieved room" and "Motor laboratory" to test and help customers accelerate time to market. Silan Integrated use of their own advantages in terms of IC product development, process production line construction, etc., systems planning and development work carried out BCD processes and products, in the process of platform, device structure, device parameter model line architecture design that four synchronized with the development, construction and reliable products and efficient technology platform. Has developed a series of power supplies and power drive products mainly include the following three aspects: AC / DC series. BCD combination Silan's superior resources and BiCMOS process platform, as well as high-voltage MOS power transistor product platform, the development of high-reliability, high-performance AC-DC series. Built-in MOS power, space-saving system, improve reliability, and cost advantages; high-pressure technology to achieve ultra-low standby power consumption starts (less than 30mW), green energy-saving mode to improve light load efficiency in order to meet the growing energy requirements of the updated Energy Star standards; Soft drivers and patented technology to optimize the EMI frequency jitter characteristics; perfect protection function, improve system reliability while simplifying peripherals. Silan products supporting these technologies are widely used in many fields phone charger, Adapter, DVD / DVB, PC power supplies. LED lighting driver circuit. 60V BCD process using high-performance DC / DC LED driver chips can be used in MR16 spotlights, lights, flat light, fluorescent; AC / DC LED driver chips can be used in high-voltage spotlights, fluorescent lamps and bulb. Which PSR + APFC program, system power factor greater than 0.95, THD less than 10%; single-stage flyback APFC program, built a unique output short circuit protection, safe and reliable system. Upcoming programs as well as non-isolated + APFC 80V buck controller chip. Brushless DC motor drive module. Has completed the first in the country to develop all the circuits and devices 600V Intelligent Power Module (IPM) need, including HVIC, MOSFET, IGBT, FRD, etc., and leading domestic module assembly technology, the introduction of a variety of variable frequency motor drive power modules, covering 20W to 2KW all motor drive applications.
