L6564

10 pin transition-mode PFC controller

Features

■ Fast “bidirectional” input voltage feedforward

(1/V2 correction)

■ Accurate adjustable output overvoltage

protection

■ Protection against feedback loop

disconnection (latched shutdown)

■ Inductor saturation protection

■ AC brownout detection

■ Low (≤100 µA) start-up current

■ 6 mA max. operating bias current

■ 1% (@ TJ = 25 °C) internal reference voltage

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

active pull-down during UVLO

■ SSOP10 package

Applications

PFC pre-regulators for:

■ High-end AC-DC adapter/charger

■ Desktop PC, server, Web server

■ IEC61000-3-2 or JEITA-MITI compliant SMPS
