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
