NCP1075NONGEVB,评估板具有 8 瓦离线双输出反激式电源,旨在为不需要与
交流电源进行输出隔离的白色家电或工业设备电路供电。该
反激式转换器是围绕 100 kHz NCP1075 单片开关
控制器设计的。利用电流镜晶体管对 (Q1) 和
齐纳二极管 (Z1) 的简单电压感测和反馈方案可在大多数典型应用中实现低成本且有效的输出调节
说明
-
NCP1075NONGEVB, Evaluation board features an 8 watt, off-line, dual output, flyback power supply intended for powering white goods or industrial equipment circuitry which does not require output isolation from the AC mains. The flyback converter is designed around 100 kHz NCP1075 monolithic switching controller. A simple voltage sensing and feedback scheme utilizing a current mirror transistor pair (Q1) and zener diode (Z1) is utilized for low cost yet effective output regulation for most typical applications
