UCC29950 - CCM PFC and LLC Combo Controller

Datasheet Summary

Description

The UCC29950 provides all the control functionality for an AC-to-DC converter with a CCM boost Power Factor Correction (PFC) stage followed by an LLC converter stage.

The controller is optimized to allow ease of use.

Features

  • 1 High Efficiency PFC and Half-Bridge Resonant LLC Combo Controller.
  • Continuous Conduction Mode (CCM) Boost Power Factor Correction.
  • Supports Self-Bias or Auxiliary (external) Bias Mode of Operation.
  • PFC Loops Fully Internally Compensated.
  • PFC Stage Design in 3 Easy Steps (design voltage feedback, current feedback and power stage).
  • Fixed 100-kHz PFC Frequency with Dithering for Ease of EMI Compliance.
  • True Input Power Limit, Independ.
