Abstract
A multi-phase DC-DC power converter is provided, which includes a pulse width modulation (PWM) controller and a plurality of output stage circuits. The plurality of output stage circuits converts an input voltage into an output voltage. The PWM controller includes a feedback circuit and a PWM generation module. The feedback circuit outputs a trigger signal according to the output voltage and a ramp signal. The PWM generation module at least generates a first PWM signal and a second PWM signal. In addition, a waveform of the first PWM signal partially overlaps a waveform of the second PWM signal at a logic high level.
