PRODUCTION DATA
In CC mode, as shown in Figure 7-8, the voltage across the LED current sense resistor, V(CSP–CSN), is regulated to the output of the programmable 8-bit CHxIADJ-DAC, scaled by the current sense amplifier voltage gain of 14. The LED current can be linearly adjusted by writing a different value to the CHxIADJ register. The 8-bit DAC output can be set in the range of 85 mV (CHxIADJ = 9) to 2.4 V (CHxIADJ = 255). The associated channel is turned off for CHxIADJ ≤ 8.
