Patent ID: 7638991

Claim:
A direct current to direct current (DC-DC) converter circuit having a direct current input, said converter circuit comprising: a first switch circuit; a second switch circuit connected in parallel with said first switch circuit; a third switch circuit; a fourth switch circuit; and control circuitry coupled to said switch circuits, said control circuitry configured to receive a direct current output voltage reference signal and utilize said direct current output voltage reference signal to select an operation of at least one of said switch circuits to generate a direct current output voltage signal of said DC-DC converter circuit, wherein said control circuitry comprises: a first output switch driver having a plurality of first control signal outputs configured to control said first switch circuit, a portion of said third switch circuit, and a portion of said fourth switch circuit; and a second output switch driver having a plurality of second control signal outputs configured to control said second switch circuit, another portion of said third switch circuit, and another portion of said fourth switch circuit.
