Claim 17:
18. A voltage converter comprising:
a plurality of capacitive voltage conversion circuits to receive an input voltage, convert the input voltage into a voltage, and output the voltage;
a common output capacitor;
a plurality of inductors coupled in series between the respective capacitive voltage conversion circuits and the output capacitor;
a plurality of voltage detectors; and
a plurality of controllers to control the respective capacitive voltage conversion circuits; wherein
each of the capacitive voltage conversion circuits includes a plurality of switches, at least one flying capacitor, and an intermediate capacitor provided at an output portion of the capacitive voltage conversion circuit;
each of the voltage detectors is configured to detect a voltage at a node that is a connection point of the intermediate capacitor and the inductor;
each of the controllers to control the respective capacitive voltage conversion circuits is configured or programmed to control the switches of the corresponding capacitive voltage conversion circuit by comparing a detection result of the voltage detector to a threshold to cause the switches to change between at least two kinds of states.
