Attributes Table
Package Style:  SOIC-16N
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
