Features and Applications

The L6564HTR is a 22.5 V, 6 mA high voltage start-up transition-mode PFC controller and is available in SOIC-14 package.

This device is suitable for applications that must be compliant with energy saving regulations and where the PFC preregulator works as the master stage.


  • Onboard 700 V startup source
  • Fast “bi-directional” 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) startup 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:
    • High-end AC-DC adapter/charger
    • IEC61000-3-2 or JEITA-MITI compliant SMPS, in excess of 400 W
    • SMPS for LED luminaires
