Claim 7:
8. An apparatus comprising:
a current-drawing load configured to receive an output voltage; and
a power converter connected to the current-drawing load, wherein the power converter comprises:
a voltage-modulating circuit that comprises one or more switches, the voltage-modulating circuit configured to receive an input voltage and provide the output voltage;
a controller coupled to the voltage-modulating circuit, wherein the controller is configured to selectively drive the one or more switches to control a level of the output voltage based on an operational mode of the voltage-modulating circuit; and
a sensing circuit connected to the voltage-modulating circuit and the controller, wherein the sensing circuit comprises one or more externally programmable connectors configured to engage a removable circuit element to change one or more boundaries of an output voltage window for operating the voltage-modulating circuit and to select the operational mode of the voltage-modulating circuit, and wherein:
when the operational mode of the voltage-modulating circuit is a pass-through mode and a voltage measurement indicates that a level of the input voltage is within the output voltage window having an upper boundary and a lower boundary, the voltage-modulating circuit is configured to control the level of the output voltage to correspond with the level of the input voltage without switching the one or more switches, and
when the operational mode of the voltage-modulating circuit is in a voltage-modulating mode and the voltage measurement indicates that the level of the input voltage is outside of the output voltage window, the voltage-modulating circuit is configured to control the level of the output voltage to differ from the level of the input voltage by switching the one or more switches.
