PN Junction Semiconductor UCC28740 | Demoboard PNDM17P650A1
65W High Voltage Auxiliary Power Supply Reference Design
Overview
| Topology | Flyback Converter |
| Input voltage | 300-1000 V |
| Output 1 | 24 V / 2.7 A |
| IC revision | 1.1 |
Description
For the power conversion system of three-phase power supply (400Vac~690Vac), a 65W/24V industrial auxiliary power supply evaluation board with a DC bus voltage range of 300Vdc~1000Vdc is designed. The use of PINJ 1700V SiC MOSFET (P3M173K0K3) can simplify circuit design, significantly improve efficiency, reduce the volume and weight of auxiliary power supply, and help industrial equipment achieve significant miniaturization, high reliability and energy saving.
Features
- Over voltage protection
- Input under voltage protection
- Over current protection
Typical applications
- EV-charger
- UPS
