If onen is going to use a dc-dc converter the Cuk converter used here is a nice
topology in that it can have low input and output ripple currents. However
input and output filters like the Murata BNX002/BNX005 series would have been
useful as would an LM3042 linear post regulator for the -12V output.. Low noise
regulators for the +12V and +5V outputs would also be useful.

I run two Trimble Thunderbolts on a LPU that uses the house 13.6
Volt supply that is backed up with two 6 Volt golf cart
batteries in series. I didn't bother installing the Anderson
Power Pole and ATX connectors, but wired directly to the circuit
board.
