    Part Number: TPS40322EVM-074 Is it possible to modify the output voltage of the TPS40322EVM-074 to give 2V@18A. The default setup is 1.2V@30A. I tried using WEBENCH POWER DESIGNER but the tool always produces a single phase design. Bill

    Hi Ridge, we are thinking of using TPS40140 for this application (even though it is an old part and no longer recommended by TI for new designs. Unfortunately the alternative suggested TPS40322 doesn't support the Vin range!). Does TPS40140 has any limitations…
