    • Evaluation Board
    • BD7682FJ-EVK-301
    • The AUX board is able to operate with both AC and DC input voltages. It is therefore possible to derive the power directly from the grid or from the system DC link

    • The BD7682FJ is an AC/DC quasi-resonant flyback controller IC from ROHM Semiconductor and offers an Auxiliary Power Supply Solution if combined with the 1700 V SiC MOSFET (SCT2H12NZ). The BD7682FJ and SCT2H12NZ combined together have been used to develop an isolated 100 W 24 V output auxiliary power solution with a very accurate voltage regulation.

    • BD7682FJ-LB-EVK-402 evaluation board outputs 24 V voltage from the input of 300 Vdc to 900 Vdc. The output current supplies up to 1 A. The BD768xFJ-LB series are Quasi-Resonant switching AC/DC converter for driving SiC (Silicon Carbide) MOSFET. Using external switching MOSFET and current detection resistors provides a lot of flexibility in the design.
