THEORY OF OPERATION The ADP8863 combines a powerful LED charge pump driver with independent control seven LEDs. These LED drivers can sink (typical) on six channels. The seventh LED can also be driven ...
Page 12
ADP8863 POWER STAGE Because typical white LEDs require drive them, some form of boosting is required over the typical variation in battery voltage. The ADP8863 accomplishes this with a high efficiency charge pump capable of ...

ADP8863 LED GROUPINGS Each LED can respond individually or be grouped together into the backlight controls. By default, all LEDs are set to be part of the backlight. This is changed by setting Bits[6:0] in Register 0x05. LEDs that are ...

ADP8863 BACKLIGHT OPERATING LEVELS Backlight brightness control operates at three distinct levels: daylight (L1), office (L2), and dark (L3). The BLV bits in Register 0x04 control the specific level at which the backlight operates. These bits can be changed manually ...
