SY5802 Datasheet (Silergy) - Single Stage Flyback And PFC Controller

SY5802, Single Stage Flyback And PFC Controller

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 efficienc

SY5802 Features

* Primary side control eliminates the opto-coupler.

* PWM or Analog Dimming.

* Valley turn-on of the primary MOSFET to achieve low switching losses

* 0.3V primary current sense reference voltage leads to
