摘要： A control circuit of a DC-DC converter has a voltage difference signal generator configured to generate a digital voltage difference signal depending on a voltage difference between the output voltage and a reference voltage, a PID controller configured to generate a digital PID signal for determining the duty ratio of the pulse-width modulated signal, based on the digital voltage difference signal, a phase controller configured to generate a digital phase control signal for determining a phase of the pulse-width modulated signal, based on the digital voltage difference signal, and a PWM generator configured to generate the pulse-width modulated signal, based on the digital PID signal and the digital phase control signal.
