Just wondering if anyone has run across a working schematic for a DC voltage regulator. Input range is 20-48 and required output is 12vdc @ 10Amps with a max of say 15-20A. I'm looking at one schematic that has the required output but is too narrow in the input voltage range. So if you know of a good one please let me know.
