DESCRIPTION

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 component count. Its power

supply is recommended to be provided by an external auxiliary supply

which will switch on and off the IC.

The circuit operates in the continuous conduction mode under average

current, and in discontinuous conduction mode only in light load

condition. The switching frequency can be set with the external resistor at

pin 4. Both current and voltage loop compensations are done externally

to allow full user control.

There are many kinds of protection features incorporated to make sure of safe system operation conditions, such as

brown-out protection, output under voltage detection and peak current limitation. The inside reference is adjusted

(5V±2%) to make sure control level and precise protection. There is a particular soft-start function to limit the start up

current and thus reduces the stress on the boost diode.
