Infineon Technologies REF62WFLY1700VSiC Reference Board

Infineon REF62WFLY1700VSiC Reference Board supports 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 +15V, -15V, and +24V with up to 62.5W output power working in a wide input voltage range from 200V_DC to 1000V_DC. Its potential applications are three-phase systems having a high input voltage DC link. The Infineon REF62WFLY1700VSiC board uses 1700V CoolSiC™ MOSFET in a TO-263 7L surface-mounted device (SMD) package as the main switch, which is well suited for high input voltage DC-link, with single-ended flyback topology. With low R_DS(on), high efficiency and low device temperature rising can be achieved with this board. The controller works in quasi-resonant mode to help reduce EMI noise.
