Claim 10:
11. A soft start overshoot prevention method for a DC/DC converter, comprising:
amplifying, by an error amplifier of the DC/DC converter, a difference between an output voltage of a DC/DC conversion circuit of the DC/DC converter and a reference voltage to generate an amplified voltage;
outputting, by the error amplifier, the amplified voltage to a pulse width modulation generator of the DC/DC converter;
generating, by the pulse width modulation generator, a pulse width modulation wave based on the amplified voltage;
outputting the pulse width modulation wave to the DC/DC conversion circuit;
controlling, by the DC/DC conversion circuit, the output voltage of the DC/DC conversion circuit based on the pulse width modulation wave;
performing, by an integration circuit of the DC/DC converter, integration processing on the difference between the reference voltage and the output voltage;
controlling, by the integration circuit, an amplitude of the amplified voltage that is input by the error amplifier to the pulse width modulation generator;
obtaining, by an overshoot detection apparatus of the DC/DC converter, an operating status parameter of the DC/DC converter; and
controlling the integration circuit to discharge based on the operating status parameter of the DC/DC converter meeting an operating status parameter requirement.
