An adjustable voltage regulator circuit, including a voltage conversion circuit, a voltage conversion controller, and a clock generator, is provided. The voltage conversion circuit receives an input voltage to generate an output voltage. The voltage conversion controller detects the output voltage, compares the output voltage with a reference voltage value, and outputs an enable signal based on a comparison result to control the voltage conversion circuit to adjust the output voltage. The clock generator generates a first clock signal and a second clock signal to respectively drive the voltage conversion circuit and the voltage conversion controller. The voltage conversion controller adjusts the enable signal to gradually adjust the output voltage to a predetermined voltage range.

Adjustable voltage regulator circuitry

A switched-capacitor DC-DC voltage converter and a control method thereof. The switched-capacitor DC-DC voltage converter comprises at least one switch array, comprising a capacitor and at least one switch group, wherein the switch group comprises a plurality of power switches connected to one another in parallel, and one end of the capacitor is electrically connected to the switch group; and a control circuit, converting an input control signal into a control signal set, and outputting the control signal set to the switch group, and the control signal set comprises a plurality of control signals with phase delayed sequentially and the duty cycle reduced sequentially.
