控制器設計的。利用電流鏡
晶體管對 (Q1) 和
齊納二極管 (Z1) 的簡單電壓感測和反饋方案可在大多數典型應用中實現低成本且有效的輸出調節
說明
-
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
