Overview

UCD3138 Power Factor Correction (PFC) firmware gets a designer through evaluation to production in power supply designs based on a PFC topology by providing all-inclusive firmware that can integrate easily with your housekeeping functionality.

Features

This firmware comes with native support for following features:

  • Innovative ZVS/Valley Switching Algorithm to boost light load efficiency and reduce THD
  • Integrated cycle by cycle protection provides protection for over voltage, over current, brownout, power-on inrush current
  • Easily re-configurable to dual-phase interleaved PFC or Bridgeless PFC
  • Integrated power metering capability eliminates dedicated power metering chip
  • 8X oversampling and innovative ZVS/valley switching improve light load efficiency & THD
  • EMI x-cap compensation to help simplify your system design.
  • Fast AC drop detection
  • Non-Linear digital control
  • Automatic current balancing for interleaved PFC
  • Current harmonic reduction by selective injection
  • Special burst mode improves efficiency
  • Duty ratio feed forward control
  • Dynamic loop compensation

 What’s Included:

  • Board support packages (BSPs)
  • User Guides
