PRODUCTION DATA
The LED current can be programmed by writing an 8-bit value to CH2IADJ Register, and as described in the Programming LED Current section.
The value of the current sense resistor, RCS, can be selected to result in the ILED(MAX) for the maximum programmed value of 255 in the CHxIADJ register.
Substituting ILED(MAX) = 1.2 A in Equation 57 results in RCS = 0.14 Ω. A current sense value of 0.1 Ω is selected for this design.
