Abstract: An electronic device may include a circuit board, at least one load circuit carried by the circuit board, and a power distribution conductor carried by the circuit board and connected to the at least one load circuit. The electronic device may also include a multiphase switching regulator including a plurality of output stages connected to the power distribution conductor, and a controller for controlling the output stages based upon respective phase currents. The respective phase currents may be derived from corresponding voltage drops across the power distribution conductor and a matrix of resistivity values.
