A switching regulator comprises a sensing module for sensing an input current of the switching regulator to generate a sensing current, a switch module for determining whether an input end is electrically connected to an output end, a first comparator for comparing a feedback signal and a reference voltage to generate a first comparison result, a compensation module for providing a compensation signal, a sawtooth wave generator for generating a sawtooth wave signal according to the sensing current, a second comparator for comparing the sawtooth wave signal and the compensation signal to generate a second comparison result, a third comparator for comparing the sawtooth wave signal and the first comparison result to generate a third comparison result, and a logic module for generating a switching signal according to the second and the third comparison results. |
