Description

LP5526 is a Lighting Management Unit for portable applications. 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. The flash outputs can drive series connected flash LED with up to 150mA of current. External PWM control can be used for dimming any selected LED outputs or it can be used to trigger the flash. The flash has also 1-second safety timer.

The device is controlled through 2-wire low voltage I2C compatible interface that reduces the number of required connections.
