Zusammenfassung:	An apparatus for determining an average current through an inductor of a regulator circuit is disclosed. A counter unit may be configured to receive a control signal, which includes a plurality of pulses, from a Power Management Unit (PMU), and determine a number of pulses received during a predetermined period of time. A pulse sampler unit may determine a duration of a given pulse of the plurality of pulses. Circuitry may be configured to determine the average current through the inductor during the predetermined period of time dependent upon the number of pulses received during the predetermined period of time and the duration of the given pulse.
