Abstract: Techniques and mechanisms for mitigating an overshoot of a supply voltage provided with a voltage regulator (VR). In an embodiment, buck converter functionality of a VR is provided with first circuitry comprising a first inductor and first switch circuits variously coupled thereto. Second circuitry of the VR comprises a second inductor and second switch circuits variously coupled thereto. In response to an indication of a voltage overshoot condition, respective states of the first switch circuits and the second switch circuits are configured to enable a conductive path for dissipating energy with the first inductor, the second inductor, and various ones of the first switch circuits and the second switch circuits. In another embodiment, mitigating the voltage overshoot condition comprises alternately toggling between two different configurations of the second switch circuits.
