    DSX12V: 12V in 12V out 10 AMPS!

    Hi all:

    I just got done designing a new DC-DC power supply that takes in 6-20 volts and puts out 12V on the output. With the output between 10-16 volts the output load can be 10 amps sustained, 13 amps peak. It is optimized for car use and will survive cranking no problem with a 10 amp load.


    It measures 1.9" by 3.5" by 1.2" and has 4 standard 0.25 inch automotive faston connectors.

    There is a power on LED and a On/Off Jumper.

    It can be ordered as a fixed output supply, or as a supply with an output range adjustable by a small pot.

    Sounds too good to be true? It's real. I even surprised myself when I measured my first sample and I measured 97.5% efficiency with a 85-watt load!

    The supply is 95+ percent efficient over the 8-15 volt range.

    Lookout. The DSX12V is pretty nice.

    -Jeff

    I must be blind or stupid after midnight, is there such a thing as pricing info or more technical info? I'd be very interested
    I have found you an argument; I am not obliged to find you an understanding.

    Pricing is going to be somewhere around 50-80 dollars. I don't know all the manufacturing costs yet. Also, mp3car store might pick it up.

    Wow, if you can hit the lower end of that price range, this combined with an M1-ATX would make a sweet cost effective combo for the higher powered AMD/P4 boards out there (assuming the power sequencing can be done right).

    Just wondering if there is such a thing as component list for your little design I am not going to compete with you promise!
    I am just figuring out all my options for senior project that is due in *gulp* 12 weeks. Thanks.

    Yaa, you can totally connect the PS_ON of the ATX connector to the PS_ON of this power supply and you'll get 12 volts at tons of amps for the VRM of a P4 Motherboard. Thats a nice application!

    I'm also thinking of other applications for it. It would make a good laptop adaptor too. I can adjust it to put out say 15 volts for example.

    If you produce a 5V POL module also, you'd pretty much have all bases covered.

    What is a POL module? How do most people use the 5 volts in this application?
