ABSTRACT:
A driving device for driving a lamp (L) includes a power stage circuit (21), a transformer circuit (22), a voltage dividing circuit (23), an inrush current sensing circuit (24), and a controller circuit (26). The power stage circuit converts a received direct current (DC) signal to an alternating current (AC) signal. The transformer circuit is connected to the power stage circuit, for converting the AC signal to an appropriate signal to drive the lamp. The voltage dividing circuit is connected to the transformer circuit, for dividing voltage of the signal output from the transformer circuit. The inrush current sensing circuit is connected to the voltage dividing circuit, for sensing inrush current output from the transformer circuit. The controller circuit is connected to the power stage circuit, for controlling output of the power stage circuit according to output of the inrush current sensing circuit.
