UCC28065 - PFC Controller

Datasheet Summary

Description

The UCC28065 interleaved PFC controller enables transition mode PFC at higher power ratings than previously possible.

The device uses a Natural Interleaving™ technique to maintain a 180-degree phase shift.

Features

  • 1 Input filter and output capacitor ripple-current reduction.
  • Reduced current ripple for higher system reliability and smaller bulk capacitor.
  • Reduced EMI filter size.
  • Higher switching frequency support.
  • Up-to 800-kHz switching frequency, reducing boost inductor size to at least one-half in size.
  • Improved input-current THD.
  • High light-load efficiency.
  • User adjustable phase management with input voltage compensation.
