Infineon Technologies ICE5GR4780AG | Demoboard REF_5GR4780AG_6W1
6 W auxiliary power supply using ICE5GR4780AG
Details
| Topologie | Sperrwandler |
| Schaltfrequenz | 125 kHz |
| Ausgang 1 | 12 V / 0.5 A |
| IC-Revision | V1.0 |
Beschreibung
The REF_5GR4780AG_6W1 is an auxiliary power supply reference design based on Infineon’s 5th generation fixed-frequency CoolSET™ family (ICE5GR4780AG) configured in a flyback topology. It utilizes a simple Zener diode reference voltage for the feedback loop and a simple input Pi filter for EMI suppression to support cost performance auxiliary power supply targeting small home appliances.
Eigenschaften
- 125kHz maximum switching frequency with 800V integrated MOSFET
- Power delivery of up to 15W with universal wide input range (85~300VAC) DCM design
- Brown in protection, fast and robust start-up operation with cascode configuration
- 3 level selectable entry/exit active burst mode profile (optional)
- Built-in digital soft-start
- Cycle by cycle peak current limitation
- Support both DCM and CCM operation with slope compensation
- Integrated error amplifier to support direct feedback typical with non-isolated flyback topology
- Digital frequency reduction with decreasing load for higher efficiency
- Adjustable line input over voltage protection (optional)
- VCC pin short to ground protection
- OLP, output short, 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
