REF62WFLY1700VSICTOBO1

REF62WFLY1700VSICTOBO1 is a 62.5W auxiliary power supply for three-phase power converter using 1700 V CoolSiC™ MOSFET in a single-ended flyback topology. The reference board was developed to support customers designing auxiliary power supplies for three-phase converters using the 1700V CoolSiC™ MOSFET in a single-ended flyback topology. The board has three outputs of +15 V, -15 V and +24 V with up to 62.5W output power working in a wide input voltage range from 200 VDC to 1000VDC. The reference board works in quasi-resonant mode and has a peak efficiency of 90.56% at a full load specification.

• Adjustable output over voltage protection
• Overload/open loop protection
• Current limit protection
• Auto restart for over temperature protection
