Abstract: In an example, a method includes storing a pending PWM pulse for a switching voltage regulator. The method also includes determining a switching voltage regulator is operating in a current limit mode, where an inductor current is above a current limit threshold. The method includes providing a predetermined number of PWM pulses in the current limit mode. The method also includes, responsive to providing the predetermined number of PWM pulses, ceasing storage of pending PWM pulses for the switching voltage regulator.
