Abstract
A switched power converter and a method are presented. The converter has a main stage with a main converter that exhibits an inductor and at least one switch to control an inductor current through the inductor. Furthermore, the switched power converter has an auxiliary stage to determine a sensed current indicative of the inductor current, and to provide or sink an auxiliary current to or from the output node, wherein the auxiliary current depends on the sensed current. In addition, the switched power converter has control circuitry to determine whether the output voltage falls below an undershoot threshold or exceeds an overshoot threshold, and to activate the auxiliary stage to provide or sink the auxiliary current, if it is determined that the output voltage falls below the undershoot threshold or exceeds the overshoot threshold.
