Thanks for the links & design pointers. I'll willing to admit that I'm
   not an expert, but always eager and willing to learn something new!
   [yes I know the lurker finally speaks...lol] I'll try yo keep this
   brief.
   A little history about my background. I was born in the chicago area a
   dual citizen (American/German[Transylvanian]), from good stock.
   Ingenuity, design, art, music, and sciences, are some of the traits I
   share with my family & relatives.
   I studied electrical engineering for 3 years in high school (graduated
   early), then 2 more in college before switching into the computer
   network field. While in college I worked at the sba patent office,
   reviewing patents and researching designs.
   Going back a little further, when I was a kid I ran a small repair
   shop, fixing tv's stereos, etc (anything with cord or ran on
   batteries). I had a real knack for fixing broken electronics so they
   wouldn't break again.
   In the early 80's I got interested in computers and have been online
   since 1985. I used to be an avid reader of 2600, and frequented the
   meeting in chicago during the 90's. [I admit I still have my first
   redbox]. It was also during this time frame I became heavily involved
   in amateur and cb radio.
   The radio experience led me down the path of becoming an On-Air
   personality, where my first radio program attracted 3 million
   listeners. :)
   I'm not afraid to learn theory and good design before embarking on a
   new electronics project or any project for that matter. I do admit to
   suffering from hobby overload from time to time, especially since I'm
   interested in almost everything. I have learned almost everything I
   know by reverse engineering.
   At my present job I am well known for having the ability to reverse
   engineer a new technical process, document it and train others.
   Lately I've found myself burning out of the network engineering field,
   so starting projects such as these help me keep things in perspective

     I doubt you want to use anything so zany :)
     What you're talking about is a relatively high power design, which
     means
     that in addition to worrying about designing the switching supply,
     you're going to have to sweat the practical details regarding PCB
     layout, et cetera.
     I'd have a look at some of the reference designs and application
     notes
     from the usual suspects ([9]onsemi.com, [10]ti.com,
     [11]maxim-ic.com, [12]linear.com),
     since they will have a lot of good practical information on getting
     the
     supply built. For example,
     [13]http://www.onsemi.com/PowerSolutions/taxonomy.do?id=448
     seems to have a substantial amount of reference material available.
     For more general information on theory and practice of dc/dc
     converter
     design, "Fundamentals of Power Electronics 2e" by Erickson and
     Maksimovic is my go-to reference. It more or less assumes you're
     already
     an electrical engineer, which may or may not be useful to you. Along
     these lines there's also "Principles of Power Electronics" by
     Kassakian
     et al, a book dear to me but certainly not to all.
     If you're looking for a gentler introduction, Google should be able
     to
     point you to a few tutorials, e.g.,
     [14]http://www.maximintegrated.com/app-notes/index.mvp/id/2031
     I've been kicking around an idea for a weird little buck converter
     controller that I haven't actually built yet. It's not particularly
     well-
     suited for kW converters, though, since the most basic form of the
     idea
     involves using a P-channel device for the high side switch. For any
     reasonable amount of power you end up wanting to use an N-ch, as
     they're
     generally higher performance devices than their P-ch counterparts
     (in
     silicon, hole mobility is about 1/3 of electron mobility, so devices
     that control electrons are generally higher performance than devices
     that control holes).
