Discloses a switching converter and a control method and a control circuit. The control circuit includes a ramp slope compensation circuit and a regulating circuit, which respectively provide the ramp slope compensation signal and adjustment signal. Value of the signal amplitude and the slope compensation signal and adjustment signal is superimposed on the ramp does not vary with changes in the duty cycle of the switching converter, thereby improving the stability of the system.
