APFC 隔离AC-DC

MT7930是一个单级、高功率因数，源边控制交流转直流LED驱动芯片。利用美芯晟科技特有的技术（已申请专利），只需极少的外围器件感应源边的电学信息，就可以精确地调制LED电流，而不需要光耦及副边感应器件。\nMT7930集成功率因数校正功能，工作在DCM（断续电流模式）和恒定关断时间模式，可以达到很小的总谐波失真电流。\nMT7930同时实现了各种保护功能，包括过流保护(OCP)、过压保护(OVP)、短路保护(SCP)和过热保护（OTP）等,以确保系统可靠地工作。  • AC85V到AC265V交流输入电压;

LCD Drivers

Overview The LC7930N, 7930NW are CMOS LSIs which incorporate 20-bit shift register, latch, and two sets of 20 LCD drivers. They also have two switching pins: one of them (channel 2) can be used as a scan-line driver (back plate) and the other (channel 1) as a segment driver. They are optimal for
