Abstract

A digital voltage regulator has an input terminal (20) coupled to an input voltage source (12), an output terminal (22) coupled to a load (14), and a plurality of switching circuits (24) to alternately couple and decouple the input terminal (20) to the output terminal (22). An estimated current is calculated for each switching circuit (24), each estimated current representing a current passing through an inductor (34) associated with the switching circuit (24). A total desired output current to pass throught the inductor (34) is calculated which will maintain an output voltage at the output terminal (22) substantially constant. The switching circuits (24) are controlled based on the estimated current and the total desired output current so that a total current passing through the inductor (34) is approximately equal to the total desired output current.
