A power controller, including power stages configured to receive input power and charge an inductor, the power stages including output power stages configured to output a first voltage and a second voltage, and feedback circuits to determine error signals of the first voltage and second voltage, a first loop configured to determine an amount of energy to be stored in the inductor using the error signals, and a second loop configured to determine a discharge of the inductor between the first voltage and the second voltage, wherein the second loop determines a moving average of at least one transition point between powering the first voltage and the second voltage.

A high bandwidth Hall sensor includes a high bandwidth path and a low bandwidth path. The relatively high offset (from sensor offset) of the high bandwidth path is estimated using a relatively low offset generated by the low bandwidth path. The relatively high offset of the high bandwidth path is substantially reduced by combining the output of the high bandwidth path with the output of the low bandwidth path to generate a high bandwidth, low offset output. The offset can be further reduced by including transimpedance amplifiers in the high bandwidth sensors to optimize the frequency response of high bandwidth Hall sensor.
