ABSTRACT:
A system and method for selecting a voltage output reference required of a DC-DC converter included in a power supply, the voltage output reference corresponding to an operating state of the power supply load. The method stores data for the voltage output reference required for each of a plurality of operating states of the load in a corresponding register. A control input that identifies an operating state of the load is received. An output of the register is selected in response to the control input. The voltage output reference required for the operating state of the load is generated in response to the selected output from the register. An apparatus for selecting a voltage output reference required by a load with a plurality of operating states includes a plurality of registers. Each of the plurality of registers has a register input and a register output, and is configurable to store data corresponding to a voltage required by the load for each of a plurality of operating states. The apparatus also includes a decoder having at least one input and at least one output. The inputs include a plurality of voltage inputs, and a control input. The output includes the voltage output reference. Each of the plurality of voltage inputs are coupled to the respective register output.
