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： Described is an apparatus which comprises: a low-side switch coupled to an output node for providing regulated voltage supply; and a first driver operable to cause the low-side switch to turn off when the output node rises above a first transistor threshold voltage. Described is also a voltage regulator which comprises: a signal generator to generate a pulse-width modulated (PWM) signal; a bridge having a low-side switch coupled to an output node for providing regulated voltage supply according to the PWM signal; a first driver operable to cause the low-side switch to turn off when the output node rises above a first transistor threshold voltage; and a bridge controller to provide control signals to the first driver. The voltage regulator may operate without diode clamps and its operation is self-timed. The voltage regulator also provides tolerance against process variation.
