摘要： 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.

摘要： Various embodiments provide a magnetic sensing scheme for a voltage regulator circuit. The voltage regulator circuit may include a first inductor (also referred to as an output inductor) coupled between a drive circuit and an output node. The voltage regulator circuit may further include a second inductor (also referred to as a sense inductor) having a first terminal coupled to the first inductor at a tap point between terminals of the first inductor. The second inductor may provide a sense voltage at a second terminal of the second inductor. A control circuit may control a state of the voltage regulator circuit based on the sense voltage to provide a regulated output voltage at the output node. Other embodiments may be described and claimed.
