Abstract
A voltage regulator circuit comprises a switching circuit configured to adjust a switching duty cycle to regulate an output voltage at an output node of the voltage regulator circuit using an error signal representative of a difference between a target voltage value and the output voltage; an inductor coupled to the switching circuit and configured to provide an inductor current to the output node; and a shunt circuit coupled in parallel to the inductor and configured to divert the inductor current away from the output node when the output voltage exceeds a specified maximum output voltage.
