Abstract
A current sensing circuit for a switched mode power converter employs a passive current sensing network coupled in parallel with the switched inductor. The passive current sensing network is impedance matched to the inductance its inherent resistance, and provides a current sensing node for single wire current sensing by a current sensing circuit. The passive current sensing network can be employed in each of a plurality of phased switching circuits that each contribute to an output of the power converter.
