Abstract
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.
