Abstract: A switching regulator includes a switching transistor, an inductor, a feedback voltage generator, a hysteresis comparator circuit, and a feedback loop circuit. The switching transistor alternately switches on and off. The inductor charges when the switching transistor is on. The feedback voltage generator generates a first feedback voltage by dividing an output voltage. The hysteresis comparator circuit has a voltage comparator to compare the first feedback voltage against a reference voltage to output a comparator output signal as a result of the comparison. The feedback loop circuit feeds the comparator output signal back to the feedback voltage generator to generate a second feedback voltage. The first feedback voltage has an alternating current component substantially dependent on the second feedback voltage varying with the comparator output signal.
