UCC28051 - Transition Mode PFC Controller

Download the UCC28051 datasheet PDF. This datasheet also covers the UCC28050 variant, as both devices belong to the same transition mode pfc controller family and are provided as variant models within a single manufacturer datasheet.

General Description

The UCC38050 and UCC38051 are PFC controllers for low-to-medium power applications requiring compliance with IEC 1000-3-2 harmonic reduction standard.

Key Features

  • 1 Transition Mode PFC Controller for Low Implementation Cost.
  • Industry Pin Compatibility With Improved Feature Set.
  • Improved Transient Response With Slew-Rate Comparator.
  • Zero Power Detect to Prevent Overvoltage Protection (OVP) During Light Load Conditions.
  • Accurate Internal VREF for Tight Output Regulation.
  • Two UVLO Options.
  • OVP, Open-Feedback Protection, and Enable Circuits.
  • ±750-mA Peak Gate Drive Current.
  • Low S.
