Design Example for Low-Cost, Low-Component 350 W PFC Front End

September 16th, 2013

PI recently introduced DER-294, a design example report for a low-cost, low-component count 350 W PFC front end using HiperPFS™-2.

Features include:

  • Complete PFC solution: controller, PFC diode, PFC Mosfet, and protection in a single IC package
  • EN61000-3-2 Class-D compliance
  • New "Cool-Pad" package reduces IC mounting hardware
  • High PFC efficiency and high power factor across wide load range that enables 80+ Gold design
  • New feature with integrated power good signal to synchronize operation with DC/DC converter stage

Performance highlights:

  • Frequency sliding maintains high efficiency across load range
  • Highly integrated PFC solution that reduces EMI and voltage stress in power components
  • Excellent transient load response with integrated amplifier
