Abstract
An electronic device adjusts power supplied to a first battery power source by a second battery power source. A battery current sense circuit senses a charge current supplied to the first battery power source. Operation of a tracking circuit depends on the charge current. A charge feedback controller generates a control voltage based on an output voltage at a first battery port of the first battery power source. A voltage converter circuit includes an input port electrically coupled to the second battery power source and an output port electrically coupled to the tracking circuit and the first battery power source. The voltage converter circuit adjusts the charge current supplied by the second battery power source through the voltage converter circuit to the first power source based on the control voltage.
