In addition, all critical parameters (i.e. current limit, frequency, PWM gain) have tighter temperature and absolute tolerances to simplify design and optimize system cost.TOP243Y uses the same proven topology as TOPSwitch, cost effectively integrating the high voltage power MOSFET, PWM control, fault protection and other control circuitry onto a single CMOS chip. Many new functions are integrated to reduce system cost and improve design flexibility, performance and energy efficiency.有关TOP243Y代理、TOP243Y中文资料、TOP243Y应用电路、TOP243Y引脚功能、TOP243Y原理图、TOP243Y型号封装、TOP243Y PDF、TOP243Y价格、TOP243Y厂家图片、TOP243Y现货供应信息，欢迎来电咨询!直线：13316887805 QQ：2501633055 范小姐
