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.
FEATURES
* 1% Precision (@ TJ = 25℃) Internal Reference Voltage * Output Overvoltage Protection * Very Low Power Start-Up Current * Current Sense Filter On Chip * Disable Function (with ZCD pin) * Transition Mode Operation * Gate Driving Current: ± 400mA * 15V Gate clamped
