The invention provides a device and control method for rapidly adjusting constant voltage output peak voltage, the device comprises a load output circuit and an adjusting control circuit, the load output circuit is used for outputting voltage Vout to the outside, and the adjusting control circuit is used for controlling the working state of the load output circuit according to a voltage signal of the load output circuit; according to the device for rapidly adjusting the constant-voltage output peak voltage and the control method, the peak voltage caused by too slow PWM adjustment due to unreasonable PID adjustment can be effectively prevented, the device can act on the output side of a main loop, and the situation that the output side voltage is too high due to sudden load change is effectively prevented by instantly connecting a dummy load, so that the output side voltage is stable and stable. The service life of an output side capacitor can be effectively maintained, and the operation stability of an output
