Im wanting to build a variable voltage input power supply so that my project can run on either 12v or 24v operation.
Im looking at using the LM2596 like in this datasheet.
https://www.ti.com/lit/ds/symlink/lm2596.pdf
I see its specs say it can handle up to 40V input, but im unclear if the design has to be modified much in the datasheet's schematic because it quotes 12V and im unsure if it would have to be changed if I am using different input voltages.
The inductor value seems to be confusing also, since to get the full 3A output, I could either use a 22uh or 68uh inductor, which are significantly different.
I see there is a link to a PSU designer and simulator in the datasheet, but it does not work when you enter any data.
TIA for any help.
