A switching power supply includes a signal generator providing a selected signal according to a first signal and a second signal, a controller generating a modulation signal in response to the selected signal, and a power converter converting an input signal into an output signal in response to the modulation signal. The first signal has a first ripple amplitude, and the second signal has a second ripple amplitude less than the first ripple amplitude.
