Classification: CPC H | IPC H

Claim 0:
1. A voltage converter comprising:
at least one 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;
at least one inductor coupled in series between the capacitive voltage conversion circuit and the output capacitor;
a voltage detector; and
a controller; wherein
the capacitive voltage conversion circuit includes a plurality of switches, at least one flying capacitor, and an intermediate capacitor at an output portion of the capacitive voltage conversion circuit;
the voltage detector is configured to detect a voltage at a node that is a connection point of the intermediate capacitor and the inductor;
the voltage detector is configured to detect a voltage relating to a difference between the voltage at the node and the input voltage; and
the controller is configured or programmed to control the switches to change between at least two states by comparing the voltage at the node to a threshold voltage.
