WS3252 General Description

WS3252 is a high-integrated offline PWM controller, optemized for high poformance low power AC/DC charger and adapter adapter application. WS3252 operates in primary-side sensing and regulation. Consequently, opto-coupler and TL431 could be eliminated, thus reduce the cost. It can achieve ± 5% const.
