Abstract

See full text

The present invention discloses a multifunctional driver controller capable to drive one or more voltage-controlled devices or current-controlled devices. According to one embodiment, the multifunctional driver controller comprises a selection unit receiving a control signal, one of a first reference voltage and a second reference voltage, the selection unit selecting either one of the first reference voltage and the second reference voltage per the control signal, and a control circuit receiving a reference voltage from the selection unit and a feedback signal from a load being driven by a controlled analog signal from the control circuit, wherein the controlled analog signal is either a controlled voltage signal or a controlled current signal, the control circuit compares the reference voltage with the feedback signal and adjusts the controlled analog signal in reference to a difference between the reference voltage and the feedback signal until the feedback signal converges to the reference voltage.
