The LMX1622-12-01 output current can be adjusted
lower by changing the value of one resistor (R18) on
the PCB. The following table shows the new output
current values:

The LMX1622-12-xx comes with a built in 5K pull-up
resistor to allow the use of an external potentiometer
for brightness adjust. In some cases this pull-up
resistor may interfere with those driving the BRITE
input from a high impedance. In this case the internal pull-
up resistor R44 may be removed from the board. Please
use the drawing below to help locate the specified resistor.
