TIDA-00776

Design files

Overview

The TIDA-00776 design  is a 350-W cost competitive power factor regulator converter designed for refrigerators and other appliances applications. This reference design is a Continuous-Conduction-Mode (CCM) boost converter that uses TI’s UCC28180 PFC controller and has all the necessary built-in protections. The hardware is designed and tested to pass the current harmonic requirement of IEC61000-3-2 (2014) for household appliances.

Features
  • Universal input from 90-VAC to 265-VAC
  • Covering IEC 61000-3-2 Class D requirements for current harmonics
  • Conversion efficiency >98.2% (Hi-line)
  • Small PCB form factor of 82mm x 80mm x 25mm
  • Enhanced dynamic response during output overvoltage and undervoltage conditions
  • Very low standby power consumption of less than 300mW

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
