Description

The L6564 is a current-mode PFC controller operating in transition mode (TM) and represents the compact version of L6563S as it embeds the same driver, reference and control stages in a very compact 10 pin SO package.

Features

■ Fast “bidirectional” input voltage feedforward (1/V2correction)

■ 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
