Claim Text:
1. A device, comprising: a charge controller to regulate an output voltage for charging a battery based on an input voltage and an input current received from an inductively coupled charging circuit, the charge controller regulating the output voltage based on a selected one of a plurality of references; a loop controller that monitors at least one of the input voltage or the input current to generate a feedback signal to the inductively coupled charging circuit to adjust the input voltage; wherein the loop controller is a first loop controller that provides a first feedback signal to the inductively coupled charging circuit based on the input voltage relative to a voltage reference, the device further comprising a second loop controller configured to provide a second feedback signal to the inductively coupled charging circuit to regulate the input current based on the input current relative to the selected reference; wherein the inductively coupled charging circuit is configured to execute a control algorithm to process the first feedback signal and the second feedback signal to adjust the input voltage to the charge controller; and further comprising a selection controller configured to select at least one of the plurality of references that is utilized by the charge controller and the second loop controller.
