POWER FACTOR CORRECTOR

DESCRIPTION

The UTC L8561 is a Power Factor Corrector, which can work in

wide input voltage range applications (from 85V ~ 265V) with an

excellent THD. It has very low start up current (about 20 uA) and

a disable function on the ZCD pin, which is designed to keep

lower current consumption in stand by mode.

The device is operating in transition mode, and is able to drive

a Power MOS or IGBT with a ± 400mA current for sourcing and

sinking.

* Output Overvoltage Protection

* Very Low Power Start-Up Current

* Current Sense Filter On Chip

* Disable Function (with ZCD pin)

* Transition Mode Operation
