Well, I woke up about a week ago and had a need for a +5VDC / +12VDC regulated switching power supply. I set out on what I thought was going to be a relatively simple journey (queried Google for a bunch of different terms) only to come up short.
Exactly what I am looking for is this:
* Input voltage will be a battery pack around 14-24 VDC with 125 AMP continuous discharge capacity (250A burst).
* I need 2 outputs: +5 VDC & +12 VDC.
* I would like them to be regulated (+/- 0.5 volts or so).
* Ideally, I'd like to have a +6.0 & +7.2 VDC output as well if that's not terribly complicated to add.
* Loads will vary significantly over time (driving large servos with high current draw).
* I expect maximum current draw to be on the order of around 120 AMPS max (each servo can draw ~5.21 AMPS at stall, we typically run around 24 servos, although it's unlikely that they ALL will hit stall simultaneously)
* I need the circuit to be very efficient, drawing these kinds of loads I need the batteries to last as long as possible.
Any help would be greatly appreciated, even if you could just point me in the right direction.
Thanks!
