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.

Claim (Index 1):
A method of operating a switched-capacitor voltage regulator to transform an input voltage level at an input node to an output voltage at an output node by allowing switching capacitor reconfiguration between an input capacitor arrangement when capacitors of the switched-capacitor voltage regulator receive charge from the input node and an output capacitor arrangement when the capacitors provide charge to the output node, the method comprising:\n receiving the input voltage level; iteratively selecting capacitor configuration settings of a plurality of capacitor configuration settings to provide a scaled output voltage within a desired output voltage range, wherein iteratively selecting the capacitor configuration settings includes:\n selecting a new capacitor configuration setting in response to a last capacitor configuration setting failing to settle the output voltage within the desired output voltage range; and \n ending the iteratively selecting capacitor configuration settings in response to a capacitor configuration of the new capacitor configuration setting settling the output voltage within the desired output voltage range; and \n interrupting switching of the capacitor configuration to permit the output voltage 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.
