Abstract
The application provides a multi-phase power converter circuit and a control circuit thereof. The multi-phase power converter circuit receives an input voltage at a voltage input terminal, outputs an output voltage at a voltage output terminal, and includes a power stage circuit. The power stage circuit is coupled to the voltage input terminal and a phase output terminal. The control circuit is coupled to the power stage circuit, the phase output terminal and the voltage output terminal, generates an error signal according to a phase current of the phase output terminal, the output voltage and a reference voltage, generates a compensation signal according to the reference voltage and the error signal, generates a ramp signal according to the error signal, and controls the power stage circuit to operate according to a predetermined duty ratio when the ramp signal crosses the compensation signal, so as to increase the phase current.
