The present disclosure provides a switched-capacitor voltage converter, a chip, and an electronic device. In the switched-capacitor voltage converter, a first branch, a second branch, a third branch, and a fourth branch are electrically connected between an input terminal and a ground terminal of the switched-capacitor voltage converter, and are further electrically connected to an output terminal of the switched-capacitor voltage converter. Transistors in the first branch and the second branch are configured to be simultaneously turned on or turned off and of different sizes, and transistors in the third branch and the fourth branch are configured to be simultaneously turned on or turned off and of different sizes. When the output terminal of the switched-capacitor voltage converter is electrically connected to a small load, the transistors in the branches may be controlled to be turned off, such that loss of the switched-capacitor voltage converter is effectively reduced.
