Abstract
An average load current calculator circuit configured for determining an average load current within an at least one phase switch mode power converter (SMPC) having at least one peak/valley detector receives an inductor current sense signal and determines and holds a peak or valley amplitude of the inductor current sense signal. A current corrector circuit receives an input voltage and an output voltage of the SMPC and an inductance value of the inductor of the SMPC for determining an average correction current of the peak or valley amplitude of the current sense. An average current generator receives the peak or valley amplitude of the current sense signal and the average correction current for determining the instantaneous average load current within a switch mode power converter (SMPC) by additively combining the peak or valley amplitude of the current sense signal and the average correction current.
