Has anyone built a boost - buck circuit?
Was thinking earlier, if you had a Morex ATX power supply.. it would be possible to survive a crank if you had a boost / buck circuit.. it would also probably solve a lot of regulation problems which could fry your Morex PSU...
Car electrical system (13.8V) -> Boost (20V) -> Buck (12V) -> Morex PSU
Something like a boost regulator to boost the car power rails to 20V or so, then buck to 12V to make a nice stable supply... Has anyone built one of these before, or found a reason why it wouldn't work?
The Morex PSU power pack is rated at less than 5A, and National's simple switchers are rated to 5A... You'd probably need a lot of caps on the output though to handle the power on current surge..
