SY58294Z中文资料照明驱动和控制IC ,Single Stage Buck PFC Regulator For LED Lighting数据手册Silergy规格书

描述 Description

The SY58294Z is a single stageBuck PFC controller targeting at LED lighting applications. It integrates a 500VMOSFET to decrease physical volume. It adopts the proprietary controlarchitecture to achieve an accurate regulation of LED current, unity powerfactor, and quasi-resonant valley turn-on high efficiency operation. It adoptsspecial design to achieve quick start up and reliable protection for safetyrequirement.

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