SY58203A1 Datasheet (Silergy) - Single Stage Flyback And PFC Regulator

SY58203A1, Single Stage Flyback And PFC Regulator

The SY58203A1 is a single stage Flyback and PFC regulator targeting at LED lighting applications.

It integrates a 700V MOSFET to decrease physical volume.

It is a primary side controller without applying any secondary feedback circuit for low cost, and drives the Flyback converter in the quasi-reso

SY58203A1 Features

* Integrated 700V MOSFET

* Primary side control eliminate to the opto-coupler.

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

* 0.3V primary current sense reference voltage leads to a lower sense resistance thus a lower conduction loss.
