need automotive DC-DC converter with multiple outputs
(OP)
Anyone have a source suggestion for an off-the-shelf DC-DC converter for an automotive test environment that can take in the "12V" input (probably more like 11V-14.4V and with appropriate load-dump protection) and output +15V (1.8A), -15V (100mA), and +7V (100mA)? It would be nice if it had a "power good" output signal as well. Or, if you know a supply that will at least do the +15 and -15, then I can use a separate regulator to derive the +7.
Thanks in advance
Thanks in advance

sreid, is there some reason that you specifically said to use a Marine inverter?

Then, just add some components to the front end to protect them from the automotive electrical system.
7V is likely not possible to find because it is an odd voltage so you'd have to make it.
ETA-USA is one company I have used in the past. There are lots of them out there.

I think you could parallel two of them to get 2 amps. According to the datasheet you can trim the voltage 10%. That's enough so you can put schottkys on the outputs and trim away the voltage drop.
Might be more economical than using an inverter.
