Techniques and mechanisms for determining a mode of operation of a switched capacitor voltage regulator (SCVR). In an embodiment, a controller supports multiple modes of operation of the SCVR, wherein the modes each correspond to a different respective sequence of switch states of a converter core of the SCVR. One of the modes is to provide boost voltage regulation with the SCVR. The controller transitions seamlessly and autonomously between two modes based on respective reference switch states of the two modes. In another embodiment, a mode transition is performed based on a signal which a control sensor generates based on a rate of switch events of the voltage regulator, and predetermined reference information indicating current characteristics of the voltage regulator.

Device, system and method to determine an operational mode of a continuous capacitive voltage regulator

In one embodiment, an apparatus comprises: a plurality of intellectual property (IP) circuits, each of the plurality of IP circuits including a configuration register to store a dynamic current budget; and a power controller coupled to the plurality of IP circuits, the power controller including a dynamic current sharing control circuit to receive current throttling hint information regarding a workload to be executed on at least some of the plurality of IP circuits and generate the dynamic current budget for each of the plurality of IP circuits based at least in part thereon. Other embodiments are described and claimed.

System, apparatus and method for dynamically controlling current consumption of processing circuits of a processor

Various embodiments provide a voltage regulator circuit with automatic phase shedding. A control circuit may control first transitions of a power state of the voltage regulator based on an average current draw of the voltage regulator. The control circuit may further control second transitions of the power state of the voltage regulator based on a voltage droop of the output voltage and/or a peak current draw of the voltage regulator. The first transitions may be performed synchronously, and the second transitions may be performed asynchronously. Other embodiments may be described and claimed.
