Claim 13:
14. The switched capacitor converter of claim 1, further comprising (2×N−1) flying capacitors, wherein N is an integer greater than 2, and wherein:
(N+2) switches of the first leg are connected in series between ground and the first voltage node;
(N+2) switches of the second leg are connected in series between ground and the second voltage node;
the first flying capacitor of the (2×N−1) flying capacitors is connected between the common node of the first switch and the second switch of the first leg, and the common node of the third switch and the fourth switch of the first leg;
the second flying capacitor of the (2×N−1) flying capacitors is connected between the common node of the first switch and the second switch of the second leg, and the common node of the third switch and the fourth switch of the second leg;
the third flying capacitor is connected between the first voltage node and the second voltage node;
one terminal of a (2×M)th flying capacitor is connected to a common node of an (M+2)th switch and an (M+3)th switch of the first leg, and the other terminal of the (2×M)th flying capacitor is connected to the common node of the first switch and the second switch of either the second leg when M is an even number, or the first leg when M is an odd number;
one terminal of a (2×M+1)th flying capacitor is connected between a common node of an (M+2)th switch and an (M+3)th switch of the second leg, and the other terminal of the (2×M+1)th flying capacitor is connected to the common node of the first switch and the second switch of either the first leg when M is an even number, or the second leg when M is an odd number, and where M is an integer between 2 and N−1;
the first upper switch is connected between the first voltage node and ground; and
the second upper switch is connected between the second voltage node and the input terminal.
