POWER FACTOR CORRECTOR

DESCRIPTION

The UTC 8561 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 50 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.
