Abstract: A power conversion circuit converting power between a bus voltage at a bus node and a first voltage at a first node includes: a bus switch coupled between the bus node and a second node which has a second voltage; plural conversion switches coupled, with at least one conversion capacitor, to the first node and the second node. In a power conversion mode, the plural conversion switches convert a power between the second voltage and the first voltage via a switched capacitor power conversion method, and plural sub-clamp circuits respectively clamping a drain-gate voltage of respective switch of a group of switches to not exceed a drain-gate clamp voltage, so that when the bus node is applied with a bus maximum rating voltage, respective drain-source voltages of the bus switch and the respective switch in the respective corresponding plural conversion switches are smaller than a corresponding breakdown voltage.

Abstract: An electronic circuit includes a first switched capacitor circuit and a second switched capacitor circuit. The first switched capacitor circuit charges and discharges a first flying capacitor to power a load. The second switched capacitor charges and discharges a second flying capacitor to power the load. When the first switched capacitor operates in a dead time, the second switched capacitor powers the load with the second flying capacitor.

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.
