SY5839 Single Stage Buck PFC Controller

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 conver.
