Abstract
(EN)
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.

L'invention concerne des techniques et des mécanismes pour atténuer un dépassement d'une tension d'alimentation associée à un régulateur de tension (VR). Dans un mode de réalisation, une fonctionnalité de convertisseur abaisseur de tension d'un VR est associée à des premiers circuits comprenant une première bobine d'induction et à des premiers circuits de commutation couplés de diverses manières à ceux-ci. De seconds circuits du VR comprennent une seconde bobine d'induction et des seconds circuits de commutation couplés de diverses manières à ceux-ci. En réponse à une indication d'un état de dépassement de tension, des états respectifs des premiers circuits de commutation et des seconds circuits de commutation sont configurés pour activer un trajet conducteur de manière à dissiper l'énergie avec la première bobine d'induction, la seconde bobine d'induction et divers premiers circuits de commutation et seconds circuits de commutation. Dans un autre mode de réalisation, l'atténuation de l'état de dépassement de tension consiste à basculer en alternance entre deux configurations différentes des seconds circuits de commutation.
