Abstract
A multi-phase controller includes a summer circuit configured to sense a plurality of phase currents generated by a plurality of power stages and generate a summed current value representative of a total current generated by the plurality of power stages; and a current limit controller configurable in a current-limit mode or a non-current-limit mode based on the summed current value and configured to limit the total current to a predefined value during the current-limit mode. The current limit controller includes a threshold selector circuit and a mode configuration circuit. The threshold selector circuit selects a first threshold or a second threshold as a selected threshold based on a configuration signal. The mode configuration circuit monitors a duration during which a comparison result indicates that the summed current value satisfies the selected threshold, and generates the configuration signal based on whether the first duration satisfies a duration threshold.
