Abstract: A method of controlling a switching power supply comprises: generating a pulse train; applying the pulse train to a switching transistor of the switching power supply to cause switching of the switching transistor on and off to convert an input voltage applied to the switching transistor to an output voltage, which rises while switching the switching transistor on and off and falls while not switching the switching transistor on and off; and performing hysteretic voltage control of the output voltage by first controlling dropping pulses of the pulse train so that the output voltage remains between hysteretic voltage thresholds including an overvoltage threshold and an undervoltage threshold that is less than the overvoltage threshold.
