Evaluation Board SY58594
Single Stage Buck PFC Controller
For LED Lighting
1. Introduction
The SY58594 is a single stage Buck PFC controller targeting at LED lighting applications. It drives the
Buck converter in the quasi-resonant mode to achieve higher efficiency. It keeps the Buck converter in
constant on time operation to achieve high power factor.
2. Application
Provide 16W~18W output power, for non-isolation LED lighting.
