L8561L-S08-R

UNISONIC TECHNOLOGIES CO., LTD L8561 Preliminary LINEAR INTEGRATED CIRCUIT 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.
