    Hi Eli,

    The TPS40210 should work in this application.

    Are you basing this on WEBENCH? Guessing so, the issue here is WEBENCH is extra conservative when selecting some of the components. For the diode it rates it for the peak current in the switch and not the average output current. In this case it is looking for a >10A diode and WEBENCH does not have any in its component database and it cannot build a design. For example if you decrease the output current to 1.5A, the diode selected is 16A. In reality typically a 3A diode is sufficient.

    If you go the solutions tab you can click on the bottom to show why parts are not found.

    Regards,
    Anthony
