Can anyone tell me what you call a "DC/DC converter" that will take any DC voltage (well say 9-30v) on the input and produce the same voltage (a small loss is OK) on the output that is isolated from the input?
Please don't say a transformer
, I don't want to dick around changing from DC/AC/DC.
I though a quick Google search would find something, and there are no end of DC/DC converters but they all have fixed OPs as far as I can see.
I'd like a PCB mount device, good for around 1-2A.
Maybe it can't be done because you have no reference across the isolation barrier, although a VCO could do that and I'm sure the Murata (or whoever) guys would be up to the job.
EDIT: Actually thinking about it 2A at 30V might be a bit of an ask. Still any ideas welcome.
