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.
FEATURES
* 1% Precision (@ T
J
= 25°C) Internal Reference Voltage
* Output Overvoltage Protection
* Very Low Power Start-Up Current
* Very Low Operating Supply Current
* Current Sense Filter On Chip
* Disable Function (with ZCD Pin)
* Transition Mode Operation
* Gate Driving Current: ± 400mA
