8561 - 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.
