8561

UNISONIC TECHNOLOGIES CO., LTD 8561 Preliminary CMOS IC 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 (@ TJ = 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 „ ORDERING INFORMATION Ordering Number Lead Free Plating Halogen Free 8561L-D08-T 8561G-D08-T Package DIP-8 Packing Tube www.DataSheet4U.com www.unisonic.com.tw Copyright © 2010 Unisonic Technologies Co., Ltd 1 of 6 QW-R502-444.a 8561 „ PIN CONFIGURATION Preliminary CMOS IC INV COMP MULT CS 1 2 3 4 8 7 6 5 Vcc GD GND ZCD „ PIN DESCRIPTION PIN NAME INV COMP MULT CS ZCD GND GD VCC DESCRIPTION Inverting input of the error amplifier.
