General Description

The SY5802 is a single stage Flyback and PFC controller targeting at LED lighting applications with PWM/Analog dimming.

It is a primary side controller without applying any secondary feedback circuit for low cost, and drives the Flyback converter in the quasiresonant mode to achieve higher efficiency.

It keeps the Flyback converter in constant on time operation to achieve high power factor.
