Abstract
An inductive current sensing method for a DC-DC switching converter is described. A sense coil is placed adjacent to a PCB track between the switching converter output and a load powered by the switching converter. A change in a magnetic field is measured around the track, generating a voltage proportional to a change in a load current. The load current is subtracted from an inductor current, when a current needed on the switching converter output is higher than a current in a steady state. In this way, output voltage undershoot or overshoot in the DC-DC switching converter is minimized.
