I am looking for a DC-DC converter design that takes a nominal 12v input, and outputs 12v also. The input voltage should be 8-15v or so... the lower the minimum, the better (6 or 7v minimum input would be great).
I need at least 2 to 3 amps output, the higher the better... 5 amps would be excellent.
It's for my car computer, which runs off 12v. This would allow it to continue running when the power dropped well below 12v during engine starting without requiring a battery backup system, as well as providing a regulated 12v output. There are similar things commercially available but most of them provide outputs for all computer voltages (+/-12, +5v, 3.3v, etc) designed to replace a computer power supply... however I already have a power supply that generates all those voltages from a single +12v so I'd rather build a simpler DC-DC to add on to the system.
I really don't know much of anything about DC-DC converter design, so I'm hoping people can offer some insight. I found a design for one of the multiple output ones, if nobody has another design handy I will probably try to reverse-engineer that one a little to get just the 12v stage from it.
I'd also be interested in any websites/articles on DC-DC power supply theory and design in general...
thanks in advance...
