| Jul 17, 2014 at 13:44 | comment | added | filthrocket | That's interesting... Many seem to be LM2596 based, which says 40v in the datasheet. But I like your thinking, I'll keep looking! (and you're right... 35v caps on the boards) | |
| Jul 17, 2014 at 13:38 | comment | added | nvd | The stuff on Ebay is mostly rated because of capacitors. As I said before, look for the IC's input voltage specs. If those specs are OK, just replace the input capacitor by a one that is rated for higher voltage. | |
| Jul 17, 2014 at 13:24 | comment | added | filthrocket | Thanks. I was hoping to use off-the-shelf pre-packaged regulators for this (e.g. cheap boards from ebay)... I think I'm right in saying these would not be isolated. Looks like I'll have to build something instead, which is a steep learning curve but might be fun! | |
