Hi I am making a PCB that has power coming into the board as 12V and 5V.
However I also need a on-board -12V power rail for some OpAmps. If I use a 12Vto12V isolated DC-DC Brick, then connect it up backwards so that output 12V is ground and output GND is 12V, would this give me the -12V that I need?
What is a better way to do this?
