LED Constant Current Module
This module provides constant current to the white
LED using regulator LP38691-ADJ. The current can be
adjusted from 2-30mA, however, typical current of 5mA
is recommended. The LED current can be measured by
measuring the voltage across R20 using test pin TP1/TP2.
The current can then be calculated with I = V/10. (Note:
The max DC current for the white LED is recommended
at 10mA).
