For all the electrical engineers out there: Do you know if they make digitally-programmable DC-DC converter modules with a wide output range? I'm looking for something that can do up to at least 12V, preferably up to 18 or 20, and that can ideally go all the way down to 0V output but I expect it'll probably have a minimum around 0.7V or something
The problem is that digital potentiometers aren't usually rated for more than 5-ish volts on their terminals.
