L8565 Overview
The UTC L8565 is a wide input range controller integrated circuit for active power factor correction. The circuit is designed for boost PFC application, and requires reduced external ponent count. Its power supply is remended to be provided by an external auxiliary supply which will switch on and off the IC.
