    I found this, that says it wouldn't hurt to put Schottkys on VDD.


    You don't need the diodes for ground, only using diodes for Vcc is sufficent....

    You could use schottky diodes as the voltage drop is 0.2V, that would be easiest.

    I suppose adding a bunch of filter caps downstream of the diodes would help reduce "fluctuations" before it enters the TPS56637.

    My Creality Ender 3 S1 Plus is a giant paperweight that can't even be used as a boat anchor, cause I'd be fined for polluting our waterways with electronic devices.

    Not as dumb as yesterday, but stupider than tomorrow!
