Description

This document is a reference design for a high-efficiency 30 W auxiliary SMPS for a refrigerator with the latest fifth-generation Infineon QR CoolSET™ ICE5QR1680BG. The power supply is designed with a universal input compatible with most geographic regions and three outputs (isolated +12 V/2.2 A, +5 V/0.2 A and non-isolated 15 V/0.15 A) as typically employed in most home appliances.

Features

  • Universal input 85~264 VAC
  • Output #1: 15 V/0.15 A
  • Output #2: 12 V/2.2 A
  • Output #3: 5 V/0.2 A

  • 85 % full-load efficiency @ 230 VAC

  • Optional AC zero crossing detection circuitry
  • Optional ON/OFF control of LDO at primary side

Typical applications

  • Telecom, Server
  • Motor control and drives
  • Home appliances
  • Auxiliary power supply for AC-DC
