ABSTRACT:
A DC power supply provides plural output voltages with respect to a common reference potential by splitting a DC input voltage potential. The input voltage is equally split into dual voltages by the embodiment described. A buffer circuit is provided between a voltage divider network and an output circuit stage coupled to the load. The buffer circuit operates to maintain a reference voltage node in the output stage at a potential substantially equal to the potential at the common node of the voltage divider network. The split voltages appear as independent power supplies to the load coupled to the power supply.
