Abstract
An automotive system includes a battery and a switching converter circuit. The switching converter circuit includes an output inductor estimator circuit coupled to a driver and a switch node of the switching converter circuit. The output inductor estimator circuit is configured to estimate inductance for an output inductor based on a comparison of sampled voltages from the switch node with voltage error values obtained using an adjustable estimated inductance parameter. The output inductor estimator circuit is configured to provide a signal indicating the estimated inductance for the output inductor.
