  • These chips look interesting.

    Variable DC regulator. 3-35V input. 1.2V-33V output. @3A

    Now I just need to find a source in sensible quantities - not the 1000 they want here!

    Mouser has them at ~$1.50 each. Seems like a circuit to output regulated 12V @10A might be in the ~$30 region. Couple that with one of the snap on 200W DC-DC convertors (either as input or just to post-regulate the 12V into the m/b) and you have a very cheap solution.

      Damn, it has been pointed out to me that this is still a linear regulator. So it still needs 2-3V above 12V to produce 12V output. Back to my searching.

        Plenty of people here have scoured the net and are fully aware of what is out there and what isn't.

        The possibility is extremely low that you are going to uncover anything that no one else has thought of.

        As I have said before, regulating the 12V line in a car is no trivial matter at all if you want anything about 3-5A of power. Even 5A of power isn't a cake walk.

          True. But there is no list available of those chips. Hence my search.
