Beschreibung
This document is a reference design for a 12 W auxiliary SMPS for a refrigerator with the latest fifth-generation Infineon QR CoolSET™ ICE5QR2270AZ. The power supply is designed with a universal input compatible with most geographic regions and isolated output (+12 V/1 A) on a single-layer PCB, as typically employed in most home appliances.
Eigenschaften
- Novel quasi-resonant switching scheme
- Rapid and adjustable start-up with cascode configuration
- 2 level selectable active burst mode level
- Built-in digital soft-start
- Cycle by cycle peak current limitation
- Digital frequency reduction with decreasing load for higher efficiency
- Adjustable line input over-voltage and brown IN/OUT protection
- VCC and CS pin short to ground protection
- OLP, output short, output over-voltage, OTP with hysteresis and VCC over/under voltage protection
- Auto-restart for all protection features
Typische Anwendungen
- Offline aux SMPS for server, PC power, aircon, refrigerator and audio / Offline main SMPS for adapter, set-top-box, water purifier, TV, industrial SMPS and POE
