Abstract
Control circuitry for controlling a current through an inductor of a power converter, the control circuitry comprising: comparison circuitry configured to compare a measurement signal, indicative of a current through the inductor during a charging phase of the power converter, to a signal indicative of a target average current through the inductor for the charging phase and to output a comparison signal based on said comparison; detection circuitry configured to detect, based on the comparison signal, a crossing time indicative of a time at which the current through the inductor during the charging phase is equal to the target average current for the charging phase; and current control circuitry configured to control a current through the inductor during a subsequent charging phase based on the crossing time.
