Abstract
A current balancing circuit is disclosed comprising a first current detector configured to measure a first current flowing from a first supply voltage to a first load, and a second current detector configured to measure a second current flowing through an inductor from a second supply voltage to the first load. The first current is compared to a first threshold to generate an error signal, and the error signal is amplified by a gain to generate a second threshold. When the first current is above the first threshold and the second current is below the second threshold, a first switch is controlled to connect a first end of the inductor to the second supply voltage. When the second current is above the second threshold, a second switch is controlled to connect the first end of the inductor to a current sink.
