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. 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 ORDERING INFORMATION Ordering Number Lead Free Halogen Free L8561L-D08-T L8561G-D08-T L8561L-S08-R L8561G-S08-R www.unisonic.com.tw Copyright © 2011 Unisonic Technologies Co., LTD Package Packing DIP-8 SOP-8 Tube Tape Reel 1 of 5 QW-R502-444.c L8561 Preliminary PIN CONFIGURATION PIN DESCRIPTION PIN NO 1 2 3 4 5 6 7 8 PIN NAME INV COMP MULT CS ZCD GND GD VCC LINEAR INTEGRATED CIRCUIT DESCRIPTION Inverting input of the error amplifier.
