Mounting Method:	Surface Mount

Features & Applications

The L6566BTR is an extremely versatile current-mode controller IC, specifically designed for high-performance offline flyback converters and also suited for single-stage single-switch input-current-shaping converters.

It supports both fixed-frequency (FF) and quasi-resonant(QR) operation where user can pick either of the two operation depending on applications needs. It features an externally programmable oscillator which defines converter's switching frequency in FF mode and the maximum allowed switching frequency in QR mode.

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
Programmable frequency modulation for EMI reduction
Latched or autorestart OVP
Brownout protection
-600/+800 mA totem pole gate driver with active pull-down during UVLO
SO-16N package

Applications:

Hi-end AC-DC adapter/charger
LCD TV/monitor, PDP
Digital consumer, IT equipment
Single-stage PFC
