    Hi Patrick,

    To be clear, is the customer making the connection at VDD & VSS from the input section to the input of the PD controller?

    The adapter circuitry (FB1, FB2, C1, C2, R4, R6, C3, R1) is referenced to RTN (the primary side of the DC/DC). It is easiest to keep this on the second board, closer to the power stage, so the RTN plane does not need to be connected to the first board.

    Thanks,
