Abstract: Voltage dividing circuitry is provided for use in a voltage converter for converting at least one input Direct Current, DC voltage to a plurality of output DC voltages. The voltage dividing circuitry including a voltage input port to receive an input DC voltage and an inductor having an input-side switch node and an output-side switch node. The output side switch node is connectable to one of a plurality of voltage output ports to supply a converted value of the input DC voltage as an output DC voltage. The flying capacitor interface has a plurality of switching elements and at least one flying capacitor, to divide the input DC voltage to provide a predetermined fixed ratio of the input DC voltage at the input-side switch node of the inductor. A voltage converter and a power management integrated circuit having the voltage dividing circuitry are also provided.

Abstract: Circuitry is provided to control a performance level of a processing device depending on two or more operating points of the processing device. An operating point has a corresponding frequency and a corresponding voltage. The performance-level control circuitry arranged to cross-multiply parameters corresponding to a first operating point and a second, different operating point of the processing device. A relative energy expenditure of the first operating point and the second operating point is determined based on the cross multiplication. An operating point of the processing device is selected depending on the determined relative energy expenditure. An apparatus having the performance level control circuitry, machine readable instructions for implementing the performance level control and a corresponding method are also provided.
