1. A voltage converter comprising:
a capacitive voltage conversion circuit to receive an input voltage, convert the input voltage into an output voltage, and output the output voltage;
an output capacitor;
an inductor coupled in series between the capacitive voltage conversion circuit and the output capacitor;
a current detector; and
a controller; wherein
the capacitive voltage conversion circuit includes a plurality of switches, at least one flying capacitor, and an intermediate capacitor provided at an output portion;
the current detector is configured to detect a current flowing in the inductor;
the controller is configured or programmed to control the plurality of switches to change between at least two states by comparing the current flowing in the inductor to a threshold current; and
the inductor is coupled in series between the intermediate capacitor and the output capacitor.
