SY5830 - Single Stage Flyback And PFC Controller

Description

The SY5830 is a single stage Flyback and 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.

Features

  • Primary side control eliminates the opto-coupler.
  • Valley turn-on of the primary MOSFET to achieve low switching losses.
  • Power factor >0.90 with single-stage conversion.
  • Reliable short LED and Open LED protection.
  • Quick start up.
