Abstract
Embodiment of the present invention may provide a switching regulator which may be located within an IC. The switching regulator couples to an external power supply, a plurality of configurable control registers, a plurality of default registers, and a multiplexer. The multiplexer is operable to select an input control signal from either the plurality of configurable control registers or the plurality of default control registers as the output control signal to the switching regulator. This default control signal, although not optimal, allows the switching regulator to be configured in a default condition during start up or power down operations and ensures that the switching regulator may provide a stable, although not necessarily optimal, power output to the various components within the IC.
