Patent ID: 8299763

Claim:
A circuit comprising: at least one regulator comprising a first inductor having an input and an output; a second inductor having an input and an output, wherein the output of the second inductor is connected to the output of the first inductor; a first array of switches (i) connected to the input of the first inductor, (ii) connected in series with the first inductor, (iii) configured to receive an input voltage from an input voltage source, and (iv) comprising a first switch and a second switch, wherein the first switch is connected in parallel with the second switch; and a second array of switches (i) connected to the input of the second inductor, (ii) connected in series with the second inductor, (iii) configured to receive the input voltage, and (iv) comprising a third switch and a fourth switch, wherein the third switch is connected in parallel with the fourth switch, wherein an output voltage of the at least one regulator is provided at (i) the output of the first inductor, and (ii) the output of the second inductor; and a controller configured to (i) detect the output voltage, and (ii) regulate the output voltage by generating control signals based on the output voltage, wherein states of the first array of switches and states of the second array of switches are controlled by respective ones of the control signals.
