Dimming Configuration using External Voltage

Dimming Configuration using External Resistance

Dimming Control Notes:

1. Io is actual output current and Ir is rated current without dimming control.

2. For the driver to operate properly, the load voltage must be maintained above the minimum voltage threshold (approx. 50% of the max. output voltage for any

given model).

3. If the output voltage is maintained above 50% of the maximum output voltage, the dimming control may be operated over the entire 1-10V range with output

current varying from 100% down to practically 10%.

4. The dimming signal is allowed to be less than 1V, however, when it for 0-1V, the output current is 10% Io.

5. The internal resistor Rin is 20K, and Vcc is about 15V.

6. Do not connect the GND of dimming to the output; otherwise, the LED driver cannot work normally.
