It is used to drive display backlights, keypad LEDs, RGB LEDs and camera flash LEDs. LP5526 can drive 2 separately connected strings of LEDs with high voltage boost converter. The RGB driver allows driving either individual color LEDs or RGB LED from separate supply power, or it can be used to drive series connecter flash LEDs from high voltage boost converter. The backlight drivers (MAIN and SUB pins) are both high resolution constant current mode drivers.
