Claim 21:
22. An integrated circuit for use in a power converter for converting an input voltage at an input of the integrated circuit into an output voltage at an output of the power converter, the integrated circuit comprising:
a plurality of phases including at least a first phase and a second phase, each of the plurality of phases comprising:
a switching node;
a first switch coupled between the input and a first node configured to couple to a first flying capacitor terminal of a flying capacitor;
a second switch coupled between the first node and the switching node;
a third switch coupled between the switching node and a second flying capacitor terminal of the flying capacitor;
a fourth switch coupled between the second node and a third node at a ground voltage; and
balancing switches comprising:
a fifth switch coupled between the second node of the first phase and the first node of the second phase;
a sixth switch coupled between the first node of the second phase and the first node of the second phase;
a seventh switch coupled between the first node of the first phase and the first node of the second phase; and
an eighth switch coupled between the second node of the first phase and the second node of the second phase.
