Abstract
A current regulator controller includes a differential amplifier that is arranged to output a current sense signal based on a differential input signal and a first stage trim signal. The current regulator controller also includes a first stage trim circuit that is arranged to provide the first stage trim signal. The current regulator controller also includes a digital-to-analog converter that is arranged to provide a set signal based on a digital input signal and a second stage trim signal. The current regulator controller also includes a second stage trim circuit that is arranged to provide the second stage trim signal. The current regulator controller also includes an error amplifier that is arranged to output an error signal based on the set signal and the current sense signal. The regulation of the current is based on the error signal.
