TPS54386EVM: Is it possible to alter parts on this evaluation board to test for <25V input?

Part Number: TPS54386EVM

Would I have to swap out the input caps or would there be more to it than that? Outputs of 5V and 3.3V would stay the same.

    Fidel,

    The inductor ripple current will increase some.  I think it is not too much though. If you increase the inductor values you reduce the ripple current you will also need to re-compensate the circuits.  I would try it with just increasing the voltage rating of the input capacitors.
