VOLTAGE CONVERTER AND VOLTAGE CONVERSION CIRCUIT INCLUDING MULTIPLE SWITCHES AND FLOATING CAPACITORS

원문 (중국어)

A voltage converter including switches includes first to fourth capacitors, each connected to an output node configured to output a charging current, and a switch controller configured to control the switches. The switch controller is configured to control the switches in response to a first voltage control signal, based on a first input voltage, having a first ratio with respect to a charging voltage based on the charging current, being applied from a voltage source, to alternatively perform a first operation of connecting the first capacitor to the voltage source, the third capacitor to ground, and the second capacitor and the fourth capacitor in series between the ground and the output node, and a second operation of connecting the first capacitor and the third capacitor in series between the ground and the output node, connecting the second capacitor to the voltage source, and connecting the fourth capacitor to the ground.
