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, a zero-crossing detection circuit, and a control logic. The PFM/PWM logic control circuit is configured to output, in response to a PFM control signal and a control signal associated with switch signals, a first PFM control signal and a second PFM control signal to a first phase circuit and a second phase circuit of the plurality of phase circuits. The PFM/PWM logic control circuit enters a first phase, a second phase, and a third phase under a light load condition or a no load condition."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multi-phase DC-DC power converter and driving method of the same","description":"A multi-phase DC-DC power converter includes an error amplifier, a comparator, a phase selection circuit, a plurality of phase circuits and a PFM/PWM logic control circuit.
