Ante, I need buid a dc/dc (psu) for my laptop, but article say: "Note that the unit MUST NOT be used with the car engine running" :( I need run for use my laptop & GPS as route navigator...
I presume this advertise is because the car alternator generate noise and Vp-p rises afecting the regulation.... ???
I tink use um 12V regulator LM7812, but need a Vin > 12 for work properly...
Some else know if is possible change this circuit, e.x. add some filter,choke, for use with engine running?
