Patent ID: 7982443

Claim:
A circuit for converting voltages, the circuit comprising: a switch circuit coupled in series with an input node and a reference node, the switch circuit comprising: at least three controllable switches coupled in series between the input node and the reference node, and a plurality of inductive low pass output stages, each inductive low pass output stage coupled to a corresponding connecting node between a corresponding pair of the controllable switches, each inductive low pass output stage configured to output an average of the voltage generated at the corresponding connecting node; and a control circuit coupled to the controllable switches, wherein: the control circuit is configured to generate a plurality of control signals for control nodes of the controllable switches, the control signals associated with a plurality of complementary periodic components having a plurality of frequencies; and each of the complementary periodic components is configured to alternately close a predetermined combination of the controllable switches to alternate a voltage at each connecting node between a voltage at the input node and a voltage at the reference node.
