Infineon Technologies ICE5AR4770AG | Demoboard REF_5AR4770AG_15W1
15 W auxiliary power supply for invertized airconditioner using ICE5AR4770AG
Overview
| Topology | Flyback Converter |
| Input voltage | 85-264 V |
| Switching frequency | 100-125 kHz |
| Output 1 | 12 V / 1 A |
| IC revision | 1.0 |
Description
This document is a reference design for a 15 W auxiliary power supply for an invertized air-conditioner unit withthe latest Infineon fifth-generation Fixed-Frequency (FF) CoolSET™ ICE5AR4770AG. The power supply isdesigned with a universal input compatible with most geographic regions and two outputs (+12 V/1 A isolated,+15 V/150 mA non-isolated) on a single-layer PCB. The PCB has a provision to add a linear regulator to support athird output (e.g. +5 V), which is connected to a +12 V output.
Features
- Integrated 700 V/ 800 V avalanche rugged CoolMOS™
- Enhanced Active Burst Mode with selectable entry and exit standby power
- Digital frequency reduction for better overall system efficiency
- Fast startup achieved with cascode configuration
- DCM and CCM operation with slope compensation
- Frequency jitter and soft gate driving for low EMI
- Built-in digital soft start
- Integrated error amplifier to support direct feedback in non-isolated flyback
- Comprehensive protection with input line over voltage protection, VCC over voltage, VCC under voltage, overload/open loop, over temperature and Current Sense (CS) short to GND
- All protections are in auto restart mode
- Limited charging current for VCC short to GND
Typical applications
- Offline main SMPS for adapter, set-top-box, water purifier, TV, industrial SMPS and POE
- Offline aux SMPS for server, PC power, aircon, refrigerator and audio
