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.
