The SY22714Z is a single stage Buck PFC controller targeting at LED lighting applications. It integrates a 500V MOSFET to decrease physical volume. It adopts the proprietary control architecture to achieve an accurate regulation of LED current, unity power factor, and quasi-resonant valley turn-on high efficiency operation. It adopts special design to achieve quick start up and reliable protection for safety requirement.

It integrates open/short LED protection and eliminates the need for opto-coupler, thus minimizing the component count and board size.
