    I am just figuring out all my options for senior project that is due in *gulp* 12 weeks. Thanks.
    Hmmm, I am guessing that's a no.
    I have found you an argument; I am not obliged to find you an understanding.

    No, I'm not going to disclose all the parts I used to make this design. I'm hoping to make some money off of it.

    You can start by taking a look at maxim semiconductor.

    Been there, done that, I had a 6 month internship last year. Like I said, I am going through my options here, I think I have an idea of what you are talking about. Thanks for the tip.

    Will you be producing aversion with your shutdown controller integrated into it? I'd be interested in that.

    The whole shabang. Basically 200W+ power supply with all the rails (from -12 to 12). This is not for sale, just a senior project for me, so at worst its going to be something to get me out of college, at best I will have a power supply for my car Looked a hell of a lot easier before I started in-depth research, the 12V rail is a pain in a butt so far. It can either be done easy and expensive (half-brick dc-dc converter costs a nice $150+) or with a bit more design than I expected. Oh well, should be a rather interesting quarter for me.

    The M1-ATX uses a LM2642 from national and a LM3478 to get to 12 volts. They buck down to 5, then boost to 12.

    Do you know much about transformer design? Or forward converter design?

    How much do you know about the different switching topologies? Can you build circuit boards? Do you have a budget?

    Unfortunately my transformer design knowledge is rather limited. My school (Cal Poly, SLO) is going through some budget cuts again, so the series of classes for power electronics I was going to take is not available to me. So most of the stuff I am having to learn for myself.
    I am familiar with the topologies of the switch-mode regulators/converters, at least with the basic ones, buck, boost, buck-boost, flyback, cuk... I know what a forward converter is, but no knowledge of how to design... but then that's what I am doing it all for, the learning process

    I can build my own circuit board (school facilities), thanks to Maxim I can probably even cut them by hand for anything with less than 20 pins My budget is err... "reasonable" I am willing to spend up to $400-500 on the whole process, that would include some equipment that school would not be willing to allow me to take home.
    So if I sound like I am up to my ears in this.. I think that would be a correct analysis. Any help always appreciated.

    Nice to see Jeff out with a PSU! I used his (your) SDC in my installation V2, worked like a charm!

    Jeff, can you design a circuit that will tell me the meaning of life? Thanks!

    Cool, glad to hear the uSDC20D is working for you. I'd love to see some pictures. I have not really gotten to see many of the controllers in action. Meaning of life.. Hmm. I've probably spent a good 4 years of my life on this car computer stuff... :-)
