1. A power converter comprising:
a plurality of power switches comprising a first switch, a second switch and a third switch sequentially connected in series between a system ground and an input voltage bus, wherein a common node of the second switch and the third switch is configured as an output terminal of the power converter, and the third switch is configured as an isolation switch including two back-to-back connected diodes and a bulk terminal, and wherein a connection of the bulk terminal is reconfigurable, and the power converter is a switched capacitor converter; and
a driver configured to drive the third switch, wherein the driver comprises a bulk switch having a bulk terminal connected to the bulk terminal of the third switch.
