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. 用于减轻由电压调节器(VR)提供的电源电压的过冲的技术和机制。在实施例中，VR的降压转换器功能被提供有第一电路，第一电路包括第一电感器和以各种方式耦合到第一电感器的第一开关电路。VR的第二电路包括第二电感器和以各种方式耦合到第二电感器的第二开关电路。响应于电压过冲状况的指
