Abstract:
Techniques for improving efficiency of a switched-capacitor voltage regulator are provided. In an example, a switched-capacitor voltage regulator can include a switched-capacitor network having multiple gain configurations, a clock configured to switch capacitors of the switched-capacitor network between a charge state and a discharge state to provide a scaled output voltage, and a controller configured to select a capacitor configuration associated with a gain of the multiple gain configurations to provide the scaled output voltage within a desired output voltage range while continuously switching the capacitor configuration, and to interrupt switching of the capacitor configuration to permit an output voltage of the switched-capacitor voltage regulator to fall below the scaled output voltage but to remain above a lower limit of the desired output voltage range to save power by reducing losses due to the switching.
