Description

This document is a reference design for a 15 W non-isolated auxiliary power supply for an outdoor airconditioner unit with the latest Infineon fifth-generation fixed-frequency (FF) CoolSET™ ICE5BR4780BZ. The power supply is designed with a universal input compatible with most geographic regions and three nonisolated outputs (12 V/800 m A, 15 V/150 mA and 5 v/300 mA), where 15 V output and 5 V output are supported by a linear regulator from an 18 V source and an 8 V source respectively.

Features

  • Universal input 85~264 VAC
  • Output #1: 15 V / 150 mA
  • Output #2: 12 V / 800 mA
  • Output #3: 5 / 300 mA
  • 75% full-load efficiency @ 230 VAC

Typical applications

  • Auxiliary power supplies for AC-DC
  • Home appliances, Residential aircon
  • Motor control and drives, Industrial drives, Industrial heating and welding
