Abstract
According to one configuration, a power supply circuit includes an inductor, a monitor circuit, a storage resource, and a processor circuit. The inductor resides in a phase of the power supply and conveys current to a load. The monitor circuit monitors and samples the voltage of a node in the power supply. The voltage of the node may be a sawtooth or ramp waveform sampled by the monitor circuit. A magnitude of the voltage at the node varies depending on an amount of current passing through the inductor to the load. The monitor circuit initiates storage of at least one sample in a storage resource. A processor circuit utilizes the multiple sample voltages stored in the storage resource to produce a value indicative of the amount of average current conveyed through the inductor to the load.
