    Hi Jim,

    The TPS53355A is a prior revision to the TPS53355D. The TPS53355D was designed to operate at an ambient temperature of 105C whereas the TPS53355A is only rated for operation at ambient temperatures of 85C. 

    As for the BOM or layout, both parts are BOM2BOM compatible and may utilize the same layout.

    Regards,
