I've been trying to hack out a solution for a circuit that requires +20v and -20v, 3-5A w/ balanced ground (obvious?) from a DC source. I've had no luck sussing out a solution so now I'm asking.
I've tried working with a 555timer voltage inverter circuit where I've got the 555 output controlling an n-ch Mosfet. I was able to create an inverted voltage, w/ 1.5v drop, but when I put into rest of circuit (+20/-20, gnd) the inverted voltage drops. If a circuit diagram will help, I can get one.
I could use any suggestions and help would be appreciated.
Any takers?
