Features and Applications

The L6563HTR is a 22.5 V transition-mode PFC controller and is available in SOIC-16 package.

This device is suitable for applications that have to be compliant with energy saving regulations and where the PFC pre-regulator works as the master stage.


  • On-board 700 V start-up source
  • Tracking boost function
  • Fast “bidirectional” input voltage feedforward (1/V2correction)
  • Interface for cascaded converter's PWM controller
  • Remote ON/OFF control
  • Accurate adjustable output overvoltage protection
  • Protection against feedback loop disconnection (latched shutdown)
  • Inductor saturation protection
  • 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


  • PFC pre-regulators for:
    • Hi-end AC-DC adapter/charger
    • IEC61000-3-2 or JEITA-MITI compliant SMPS, in excess of 400 W
  • SMPS for LED luminaires
