Introduction

AI Translation

The SY5839 is a single stage Buck PFC controller targeting at LED lighting applications. It is a primary side controller without applying any secondary feedback circuit for low cost, and drives the Flyback converter in the quasi-resonant mode to achieve higher efficiency. It keeps the Flyback converter in constant on time operation to achieve high power factor. It adopts special design to achieve quick start up and reliable protection for safety requirement.
