摘要： A control device for a multi-phase DC-DC converter is disclosed. The multi-phase DC-DC converter includes a plurality of converting channels. The control device includes an error amplifier for comparing a feedback signal of the multi-phase DC-DC converter and a reference signal to generate a comparison result, a main comparator for comparing the comparison result and a first sawtooth signal corresponding to a first converting channel of the plurality of converting channels to generate a first PWM signal, and at least one computing module each corresponding to one of the plurality of the converting channels, for generating a PWM signal according to the comparison result, a corresponding sawtooth signal, a corresponding sensing signal, and a sensing signal corresponding to a previous converting channel of the converting channel to control the converting channel.
