Hi,
Another issue, is the easiest way to convert a +12Vdc input to both +12Vdc and -12Vdc to power some op-amps and video switchers. The issue is, I will also need to power some 7805/7905 regulators off those supplies for PICs and some opamps at the lower voltage. I need to be able to source quite a bit of current therefore and the usual devices I come across will only provide 100mA or so at maximum which isn't enough. Any circuits out there to generate this for me reliably with at least 200mA of current on the -12Vdc rail?
Cheers
