Abstract: This disclosure describes techniques to control switching operations of a switching regulator. The disclosure includes a system comprising a switching regulator configured to use an inductor to generate an output voltage signal from a. pulse-width-modulated (PWM) signal by controlling one or more switches of the switching regulator that vary charging operations of the inductor; transient handling circuitry coupled to receive a feedback voltage based on the output voltage signal and configured to generate first and second current signals that represent a difference between the feedback voltage and a reference voltage; and control circuitry configured to generate the PWM signal based on the first and second current signals such that the first current signal changes a frequency of an oscillator used to generate the PWM signal and the second current signal changes a bandwidth of a feedback loop associated with the switching regulator.
