Abstract
A multi-phase parallel converter can include: sampling circuits corresponding to power stage circuits to form a plurality of phases of the multi-phase parallel converter, where each sampling circuit samples an inductor current of a corresponding power stage circuit, and generates a sense signal; a current-sharing circuit that generates a current-sharing control signal according to a superimposed signal that is generated by adding the sense signal to a bias voltage signal; switching control circuits corresponding to the power stage circuits, where each switching control circuit receives the current-sharing control signal, and controls a switching operation of a corresponding power stage circuit; and a bias voltage generator that generates the bias voltage signal to gradually increase/decrease when a selected phase is to be disabled/enabled.
