Abstract
A digital switching voltage regulator 10 for providing regulation about a single voltage despite the current supplied thereby is disclosed herein. The digital switching voltage regulator 10 of the present invention includes a first voltage regulation module 12 for regulating, within a first voltage regulation window RW1 defined by first upper and lower threshold voltages, the voltage across a load 21 operatively coupled to the regulator 10. The regulator 10 of the present invention further includes a second voltage regulation module 14 for regulating the voltage across the load 21 within a second voltage regulation window RW2 defined by second upper and lower threshold voltages. The second voltage regulation window 14 is included within the first voltage regulation window 12 and, in a preferred embodiment, the first and second regulation windows RW1 and RW2 are centered about a common voltage.
