    Hi Eric,

    A couple of comments regarding the schematic.

    FDMQ8205A is currently no stock on Mouser and Digikey. If you cannot wait and must need a solution sooner, I recommend doing a discrete FET bridge solution like in TPS2373-4EVM-758.
    The dummy load circuit is not needed. The TPS2372 has a feature called "automatic MPS" which is internal to the part and can make the MPS signal automatically if the load is too low. You do have to use the AMPS_CTL in order to implement this feature.

    The DCDC design looks good.

    Thanks!
    Regards,
    Darwin
