Abstract
The present invention relates to a driver system, comprising a counter unit, a buffer unit and a voltage regulation unit. The counter unit is adapted to sequentially activate one of the first output terminals upon receiving a driver signal and then output a control signal according to the driver signal. The buffer unit is adapted to output an isolated control signal upon receiving the control signal from the counter unit. Upon receiving the isolated control signal, the voltage regulation unit outputs a control voltage which corresponds to a given resistor provided therein. The control voltage is useful in driving an electronic device, and the operation of the electronic device may be further adjusted by changing the control voltage from one level to another.
