Product Overview

The UCC28063EVM-723 is a fully assembled and tested circuit for evaluating the UCC28063 natural interleaving transition mode PFC controller. The evaluation module is an off line 300W PFC pre regulator that runs of a universal line input of 85V to 265V RMS and provides a regulated 390V output. The evaluation module demonstrates how the UCC28063 IC can be used in an interleaved transition mode PFC pre regulator.
  • Phase management capability
  • FailSafe OVP with dual paths prevents output over voltage conditions by voltage sensing failures
  • Soft start on overvoltage
  • Integrated brownout
  • Input filter and output capacitor current cancellation
  • Enables use of low cost diodes without extensive snubber circuitry
  • Improved light load efficiency
  • Improved transient response
  • Complete system level protection
  • 1A Source/1.8A sink gate drivers
