Claim 0:
1. An apparatus comprising:
an input terminal, a reference terminal, and an output terminal;
a controller; and
at least one series string of switches connected between the input terminal and the output terminal, wherein each of the at least one series string of switches comprises:
a first switch connected between the input terminal and a first common terminal;
a second switch connected between the first common terminal and an intermediate node;
a third switch connected between the intermediate node and a second common terminal;
a fourth switch connected between the second common terminal and the output terminal;
at least one first capacitor connected between the first common terminal and the second common terminal; and
an inductor connected between the intermediate node and the reference terminal;

wherein the controller is configured to cause the apparatus to output a voltage between the reference terminal and the output terminal by switching, at a first frequency, the first, the second, the third, and the fourth switches of each of the at least one series string of switches, wherein the switching in each of the one series string of switches includes:
during each first half period of the first frequency, turn on the first and the third switches, and turn off the second and the fourth switches; and
during each second half period of the first frequency, turn on the second and the fourth switches, and turn off the first and the third switches, wherein the turning off of the third switch is prior to the turning off of the first switch.
