GP8511
Single Stage Buck PFC Controller for LED Lighting
Description
Features
The GP8551 is a single stage Buck PFC controller targeting at LED lighting applications. It integrates a 600V 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 integrates open/short LED protection and eliminates the need for opto-coupler, thus minimizing the component count and board. GP8551 is offered in 8-SOP package.
•- Built-in 600V Power MOSFET •- Valley turn-on of the MOSFET to achieve •low switching losses •- 0.3V current sense reference voltage •leads to a lower sense resistance thus •a lower conduction loss.
