ICE3AS03LJG reference design

This document is an engineering report that describes a universal input power supply designed in a 19.5V 65W off line flyback converter that utilizes the F3 PWM controller ICE3AS03LJG. The application board is operated in discontinuous current mode and running at 100 kHz switching frequency. It has one output voltage with secondary side control regulation. It is especially suitable for AC/DC power supply such as LCD monitors, adapters for printers and notebook computers, DVD players and recorder, Blue-Ray DVD player and recorder, set-top boxes and industrial auxiliary power supplies. The ICE3AS03LJG is a current mode PWM controller. With the 500V startup cell, active burst mode and BiCMOS technologies, the standby power can be
