Abstract
An exemplary driving apparatus capable of generating a driving current, including: an analog input generating circuit, an analog input driving circuit, and an output circuit. The analog input generating circuit is electrically connected between a first voltage source and the ground and configured (i.e., structured and arranged) for supplying an adjustable analog signal. The analog input driving circuit is electrically connected between a second voltage source and the ground and configured for converting the analog signal into a pulsed signal. The output circuit is configured for converting the pulsed signal into a driving current as an output. The frequency of the pulsed signal can be adjusted via adjusting the analog signal and thereby varying the driving current. Thus the driving current can be adapted for the different target loads.
