Hey folks.
Just wondering if these Buck modules are good or not, and why?
Those particular models have caused much grief in the past.
They are NOT recommended.
What kind of current loads are you anticipating and what is your “high” voltage input?
24V and 5V out with 4Amps going in
So you’re looking to handle ~100W for a buck converter or 24V->5V with a 20A output.
That’s pretty hefty, although they do exist: Hi power buck converter
Nothing you buy will actually reach the quoted current levels over the long term, so either pick something larger to allow for derating or use multiple smaller units (or both).
