    摘要: 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, the flying capacitor interface 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.

    摘要: A Computational Digital Low Dropout (CDLDO) regulator is described that computes a required solution for regulating an output supply as opposed to traditional feedback controllers. The CDLDO regulator is Moore's Law friendly in that it can scale with technology nodes. For example, CDLDO regulator of some embodiments uses a digital approach to voltage regulation, which is orders of magnitude faster than traditional digital LDOs and enables regulation at GHz speeds, making fast dynamic DVFS a reality. The CDLDO also autonomously tunes out the effects of process-voltage-temperature (PVT) and other non-idealities making the settling time totally variation tolerant.
