Abstract: A switched capacitor converter circuit includes: plural capacitors and plural switches which switch the connections of the plural capacitors periodically. In a first period, the plural switches control a first capacitor to be electrically connected between a first power and a second power, and control a second capacitor and a third capacitor to be electrically connected in series between the second power and a ground level. In a second period, the plural switches control the first capacitor and the second capacitor to be electrically connected in series between the second power and the ground, and control the third capacitor and the second capacitor to be electrically connected in parallel with the second power, thereby a second current of the second power is 4 times of a first current of the first power.
