L6566A

Multi-mode controller for SMPS with PFC front-end

Features

■ Selectable multi-mode operation:

fixed frequency or quasi-resonant

■ On-board 700 V high-voltage start-up

■ Advanced light load management

■ Low quiescent current (< 3 mA)

■ Adaptive UVLO

■ Line feedforward for constant power capability

vs mains voltage

■ Pulse-by-pulse OCP, shutdown on overload

(latched or autorestart)

■ Transformer saturation detection

■ Switched supply rail for PFC controller

■ Latched or autorestart OVP

■ Brownout protection

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

active pull-down during UVLO

■ SO16N package

Applications

■ Notebook, TV and LCD monitors adapters

■ High power chargers

■ PDP/LCD TV

■ Consumer appliances, like DVD, VCR, set-top

box

■ IT equipment, games, aux. power supplies

■ Power supplies in excess of 150 W
