The present invention provides a soft start circuit and a DC / DC converter, wherein the soft start circuit comprises a ramp voltage circuit, a differential input circuit, a load amplifier circuit, a switching circuit and a positive feedback hysteresis circuit. When the soft start circuit is powered on, the ramp voltage circuit outputs a ramp voltage that changes and rises, and when the voltage difference between a reference voltage and the rising ramp voltage reaches a preset difference, the differential input circuit outputs a second current signal, and outputs a second switching signal after being amplified by the load amplifier circuit. The positive feedback hysteresis circuit increases the flipping speed of the second switching signal, so that the second switching signal quickly reaches the switching threshold of the switching circuit. Since the ramp voltage is less than the reference voltage at this time, during the signal output delay period, even if the ramp voltage continues to rise, the soft start circuit can be adjusted according to the signal delay time and the rising speed of the ramp voltage to ensure that the ramp voltage is less than the reference voltage when the switching circuit is switched, thereby avoiding output overshoot during switching.
