I bought some buck converters (up to 24V in, down to 3v out) for a project, but when it was time to lay them out on my stripboard, the holes didn't line up. Not even close. I've now spent over an hour searching for something similar, but with 0.1 inch hole spacing. Any suggestions? Thanks!

 

Not much info to go on. This one will provide 500mA.

There's various TO220 style buck regulators with 5 or so pins that work up to 1A and usually include fixed output voltage versions (LM2575 from foggy memory). Loosely branded as replacements for the linears, but you have to add inductor, catch diode and the output filter cap needs to be a bit more fancy.

 

here are quite a lot available now. Like...

Thanks, everyone! I didn't know what term to add to my search to get the 0.1" pin / hole spacing. One of these will surely do the trick.

A large proportion of through hole parts are 0.1" pitch - but you may need to convert it to metric to search it.

Now why didn't I think of that? (Seriously - when I used "2.54" in the search, I found a ton.) Thanks!
