Claim 0:
1. A DC/DC converter, comprising:
a DC/DC conversion circuit;
an overshoot detection apparatus;
a pulse width modulation generator;
an error amplifier; and
an integration circuit connected to an output port of the error amplifier;
wherein the error amplifier is configured to: amplify a difference between an output voltage of the DC/DC conversion circuit and a reference voltage to generate an amplified voltage, and output the amplified voltage to the pulse width modulation generator;
wherein the pulse width modulation generator is configured to: generate a pulse width modulation wave based on the amplified voltage, and output the pulse width modulation wave to the DC/DC conversion circuit;
wherein the DC/DC conversion circuit is configured to control the output voltage of the DC/DC conversion circuit based on the pulse width modulation wave;
wherein the integration circuit is configured to: perform integration processing on the difference between the reference voltage and the output voltage, and control an amplitude of the amplified voltage that is input by the error amplifier to the pulse width modulation generator; and
wherein the overshoot detection apparatus is configured to:
obtain an operating status parameter of the DC/DC converter, and
control the integration circuit to discharge based on the operating status parameter of the DC/DC converter meeting an operating status parameter requirement.
