Abstract
A ripple-based control switching regulator includes a switch, an inductor, a capacitor, an output voltage processing unit and a control unit. Where the switch is utilized to output selectively output a first reference voltage or a second reference voltage as an output voltage according to a control signal. The inductor is coupled to the switch, and produces an inductor output voltage according to the output voltage. The capacitor is coupled to the inductor. The output voltage processing unit is used to output a processed inductor output voltage according to the output voltage and the inductor output voltage. The control unit is used to output the control signal according to at least the processed inductor output voltage.
