    Free DC-DC Power Supply Design

    If anyone wants a cheap and relatively easy to build DC-DC power supply design, I have put up my design for your viewing pleasure at:

    http://www.sproggy.freeserve.co.uk

    The site is very basic at the moment but includes some pictures of my completed unit, the schematic and the pcb layout.

    Merry Xmas

    Hello there mate

    Nice DC PS.
    However your +12 is not a flyback circuit which means it cant hand input voltage from 8
    volt. Min input voltage should be > 12.5volts
    So the computer will restart everytime you start your car. But other then that its a classic design!

    Sorry, but I don't intend on selling completed power supply units.

    If there is enough interest I may be able to get batches of PCB's made for you to build your own supplies.
