Abstract: The present disclosure provides an asymmetric switching capacitor regulator that is capable of providing an output voltage, covering a wide voltage range, with a high efficiency. The disclosed switching capacitor regulator is configured to generate a wide range of an output voltage by differentiating a voltage across one or more switching capacitors from a voltage across the rest of the switching capacitors in the switching capacitor regulator.

Abstract: The present disclosure shows a hybrid regulator topology that can be more easily integrated and that can maintain high efficiency across a wide output and input voltage range, even with a small inductor. The hybrid regulator topology can include two types of regulators: a flying switched-inductor regulator and a step-down regulator that divides the input voltage into an M/N fraction of the input voltage. The disclosed embodiments of the hybrid regulator topology can reduce the capacitive loss of the flying switched-inductor regulator by limiting the voltage swing across the switches in the flying switched-inductor regulator. The disclosed embodiments of the hybrid regulator topology can reduce the inductor resistive loss of the flying switched-inductor regulator by operating the flying switched-inductor regulator at a high switching frequency and with a small amount of current flow through the inductor.
