WEBENCH® Tools/AM5728: AM5728 power solution - Schotky diode

Part Number: AM5728
Other Parts Discussed in Thread: TPS54531

Tool/software: WEBENCH® Design Tools


I'm using the AM5728 reference design power solution otherwise but instead of 12V DC-IN, I'm using 12V to 24V input voltage. Max 24V.

I have changed capacitors etc. according to higher 24V but how about TPS54531D schottky diode. Is it still safe to use SK54AFL-TP as on ref. design? Component references are D1, D2 and D24.

Simulations are giving bigger diodes even the current from all the TPS54531 components are quite the same as on reference design. Anyway, I can't find SK54AFL from the webench tool at all.

I am comparing the SK54AFL to bigger package version B540C-FDICT-ND which is suggested by webench and the values are same. Only the package is smaller. So I suppose the SK54AFL is ok to be used? Or is there some current limit when to choose the bigger package?
