If you don’t agree with the concept that if there is a demand, there must be a supply, you will never receive your desires. For more 12 volt power supplies of all styles click here. An interesting possible use for the -12V line would be use it in conjunction with the +12V rail and run. 3 VDC, +5 VDC, -5 VDC (optional), +12 VDC, and -12 VDC lines across multiple pins. A good power supply is essential to electronic projects. supply curve. negative voltage, there is no need for additional amplifier to generate the positive voltage and there is no potential damage of ESD diode using buck-boost type converter. DIY variable power supply Few years ago I modified a salvaged ATX power supply to a fixed voltage bench power supply. This implies a leftward shift of supply. They take 100-240Vac 50/60Hz input and output 3. In general, logic IC's will be unipolar in operation.
