ABSTRACT:
The invention provides a monolithic, highly integrated power supply circuit capable of providing various voltages for circuits on an expansion card, either from a main supply source or an auxiliary supply source. The monolithic power supply circuit preferably includes two switching converters, two low-drop-out regulators, a standby regulator, a reset circuit, and a control circuit. An associated method for providing various voltages via a monolithic power supply circuit is also disclosed.
