Abstract
An apparatus includes a power converter and an estimator. The power converter produces an output voltage to power a load via current through an inductor. The estimator receives a current sense signal from a current monitor resource. The current sense signal represents/indicates a measured magnitude of the current supplied to the load through the inductor over time during one or more power delivery control cycles. Portions of the current sense signal may be an inaccurate representation of an amount of current through the inductor. Via the current sense signal, or portion thereof, the estimator determines (such as calculates) an inductance (value) of the inductor. The estimator then uses the calculated inductance value to estimate a magnitude of the output current supplied through the inductor to the load.
