Introduction

AI Translation

OB3635Ex is a primary-side-control and high power factor, low THD fly-back PWM controller specialized for LED lighting application. It operates in primary side sensing and regulation without auxiliary winding. OB3635Ex works at Quasi-Resonant operation with maximum working frequency clamping, which can improve the efficiency of LED lighting system design.
