Claim 32:
33. A power converter for converting an input voltage at an input of the power converter into an output voltage at an output of the power converter, the power converter comprising:
a first power converter branch comprising a first capacitor, a first switch network, and a first inductor, the first switch network arranged to selectably couple the first capacitor between an input voltage, a first reference voltage, and a first terminal of the first inductor, wherein a second terminal of the first inductor is coupled to an output node;
a second power converter branch comprising a second capacitor, a second switch network, and a second inductor, the second switch network arranged to selectably couple the second capacitor between the input voltage, a second reference voltage, and a first terminal of the second inductor, wherein a second terminal of the second inductor is coupled to the output node; and
a third switch network between the first power converter branch and the second power converter branch, wherein the third switch network is arranged to selectably couple the first and second capacitors in series or in parallel, to allow enable charge balancing between the first capacitor and second capacitor.
