Abstract:
A lighting driver ( 300, 400 ) for driving at least one lighting device ( 120 ) includes a control unit ( 310, 410 ) disposed on a first side of an electrical isolation barrier ( 320, 420 ), and a power supply unit ( 350, 450 ) disposed on a second side of the electrical isolation barrier so as to be electrically isolated from the control unit. The control unit supplies a single enable signal ( 302, 402 ) across the electrical isolation barrier to the power supply unit. The power supply unit includes a switching circuit (S 1/ S 2 ) configured to selectively enable and disable, in response to the single enable signal, two output voltages for supplying power to an external device ( 130 ) which communicates data with the lighting driver.

Claim (Index 6):
The lighting driver of  claim 5 , wherein the switching circuit (S 1 /S 2 ) includes a first switch (S 1 ) and a second switch (S 2 ), wherein the first switch is connected between the auxiliary voltage and the positive voltage side of the DALI bus, wherein the second switch is connected in series with the common line connected to the external device, and wherein the power supply unit further comprises:\n a filter configured to supply a control signal to a control terminal of the second switch (S 2 ) in response to the single select signal to turn on the second switch (S 2  and supply the auxiliary voltage to the external device when the single enable signal to turn on the second has the steady low voltage level and when the single enable signal is the PWM signal, and to turn off the second switch and disable supply of the auxiliary voltage and the DALI supply voltage to the external device when the single enable signal has the steady high voltage level; a detector configured to detect whether the single enable signal is the PWM signal; and a voltage doubler which doubles a peak voltage of the PWM signal and supplies the doubled peak voltage to a control terminal of the first switch (S 1 )) to turn on the first switch and supply the DALI supply voltage to the external device when the single enable signal is the PWM signal, and to turn off the first switch and disable supply of the DALI supply voltage to the external device when the single enable signal has the steady low voltage level.
