Voltage regulator circuit

Abstract

A method for operating a voltage regulator circuit for converting an input voltage into an output voltage comprising an input port for receiving an input voltage, an output port for providing an output voltage, an output voltage reference circuit configured to output a reference voltage, an overshoot detection device, an inductive device, and an overshoot reduction control circuit comprising a peak comparator device, the method comprising: in response to detecting, by the overshoot detection device, that the output voltage exceeds a first threshold, generating a first control signal configured to turn on an overshoot reduction function configured to reduce the output voltage; determining when to end the overshoot reduction function by: detecting, using the peak comparator device if the output voltage crosses a second threshold and; if the output voltage is detected to have crossed the second threshold, generating a second control signal configured to control the overshoot protection function to end.
