In accordance with aspects of the present invention, a power control circuit includes a MAIN window comparator circuit providing a MAIN signal; an AUX window comparator circuit providing an AUX signal; a state machine receiving the MAIN signal and the AUX signal; a MAIN slew circuit coupled to drive a MAIN switch, the MAIN switch coupled between MAIN and an output; an AUX slew circuit coupled to drive an AUX switch, the AUX switch coupled between AUX and the output; wherein the state machine operates to continuously activate either the MAIN switch or the AUX switch according to the MAIN signal and the AUX signal such that the output is continuously coupled to either a MAIN input or an AUX input with minimum disruption to output voltage, input and output capacitance inrush currents or reverse conduction. What really makes the circuit unique is it is combined with an adjustable forward biased rectification circuit for each channel of MAIN and AUX.

In accordance with aspects of the present invention, a programmable power management integrated circuit is presented. An integrated circuit can include a plurality of cells, each cell including at least one driver for a switchable element; and a switch matrix and controller coupled to the plurality of cells, the switch matrix and controller being programmable to configure at least one power channel, each power channel including at least one cell of the plurality of cells. A method of providing a power management system using the integrated circuit includes receiving power requirements corresponding to a target device; providing implementation options to achieve the power requirements; selecting a solution from the implementation options; generating a programming file for a power management integrated circuit, and generating a printed circuit board design for the power management integrated circuit.
