Abstract
A multi-phase DC-DC power converter includes an error amplifier, a comparator, a phase selection circuit, a plurality of phase circuits and a width detecting circuit. The plurality of phase circuits are each associated with a phase of the multi-phase DC-DC power converter, each including a turn-on clock generation circuit, a first switching transistor, a second switching transistor, an output inductor, and a control logic. In a load transition state, when the width detecting circuit detects that a comparison output signal exceeds a predetermined width, the phase selection circuit adjusts one of the plurality of phase signals based on a force trigger signal, and outputs, corresponding to a force trigger signal, one of the plurality of on-signals.
