Abstract
A combination of inductor current thresholds and circuitry for controlling the inductor based on the thresholds may be implemented in a power converter. One or more of the inductor current thresholds may be variable. An inductor current threshold may be varied as part of a search algorithm for identifying a value resulting in full scale operation of the inductor without exceeding a safe limit. After each cycle of the power converter, circuitry may determine which current thresholds have been exceeded and which have not been exceeded and then generate indication signals for each of the thresholds. Control logic may receive the indication signals and adjust one of the inductor current thresholds used to determine timing for disconnecting and reconnecting current through the inductor of the power converter.
