Abstract
A DC/DC converter includes a soft start overshoot prevention mechanism. The DC/DC converter includes 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. The integration circuit is configured to perform integration processing on a difference between a reference voltage and an output voltage of the DC/DC conversion circuit, and control an amplitude of an amplified voltage that is input by the error amplifier to the pulse width modulation generator. The overshoot detection apparatus obtains an operating status parameter of the DC/DC converter, and controls, when the operating status parameter of the DC/DC converter meets an operating status parameter requirement, the integration circuit to discharge.
