NCP1075NONGEVB: 8W, DUAL, NON-ISOLATED EVALUATION BOARD
This 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 ON Semiconductor's 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.This particular design example provides output voltages of 5V and 8.5V but these can be tailored to other voltages to accommodate the specific requirements by appropriate transformer turns ratio changes and alterations to voltage setting zener Z1 and resistor R6.
