Feature Description (continued)
Figure 5. Illumination Control Loop
Within the illumination block, the following blocks can be distinguished:
•
Programmable gain block
•
LDO illum: analog supply voltage for internal illumination blocks.
•
Illumination driver A: primary driver using internal FETs.
•
Illumination driver B: secondary driver – for future purpose; will not be discussed.
•
RGB stobe decoder: controls the on-off rhythm of the LEDs and measures the LED current.
7.3.2.1 Programmable Gain Block
The current through the LEDs is determined by a digital number stored in the respective IDAC registers 0x03h to
0x08h. These registers determine the LED current which is measured through the sense resistor RLIM. The
voltage across RLIM is compared with the current setting from the IDAC registers and the loop regulates the
current to its set value.
