SY58282N中文资料Buck Regulator For LED Lighting数据手册Silergy规格书

描述 Description

The SY58282N is a Buck regulator 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 and Quasi-Resonant valley turn-on for high efficiency operation. Proprietary self-bias technique saves the bias supply and reduces the start up time.
It integrates open/short LED protection and eliminates the need for opto-coupler or auxiliary winding (in floating switch application), thus minimizing the component count and board size.
