Hi all,
Im trying to repair an old piece of audio gear
it has a DC-DC convertor in it, and encapsulated one
its small, gives me +5v and -8.5v
so im gonna use one that gets me +9 and -9 v out and send the +9 into a 7805
anyway... on the circuit board, the input ground and the output ground are one, does that mean its is UN-ISOLATED?
and if i use an isolated one, and tie the input ground and output 0v together all should be fine?
mitch
