The LTC3208 is a multi-display LED driver, using a high-efficiency, low
noise charge pump to provide power to 5 channels (MAIN, SUB, RGB, CAM,
AUX). Current for each LED is controlled by the I2C serial interface.
Four AUX current sources can be independently assigned via the I2C port
to the CAM, SUB, MAIN, or AUX DAC controlled displays
