L6563A

Advanced transition-mode PFC controller

General features

■ Transition-mode control of PFC pre-regulators

■ Very precise adjustable output overvoltage

protection

■ Tracking boost function

■ Protection against feedback loop failure

(Latched shutdown)

■ Interface for cascaded converter's PWM

controller

■ Input voltage feedforward (1/V2)

■ Remote ON/OFF control

■ Low (

≤90µA) start-up current

■ 5mA max. quiescent current

■ 1.5% (@ TJ = 25°C) internal reference voltage

■ -600/+800 mA totem pole gate driver with

active pull-down during UVLO

■ SO14 package

Applications

PFC pre-regulators for:

■ HI-END AC-DC adapter/charger

■ Desktop PC, server, WEB server

■ IEC61000-3-2 OR JEIDA-MITI compliant

SMPS, in excess of 250W
