The LP5521 is a three channel LED driver designed to produce a variety of lighting effects for mobile devices. A high efficiency charge pump enables LED driving over full Li-Ion battery voltage range. The device has a program memory for creating variety of lighting sequences. When program memory has been loaded, the LP5521 can operate independently without processor control

The LP5521 Evaluation Kit is based on a computer controlled system, where the actual LP5521 devices are controlled and powered through the USB interface. Also, external power can be used if wanted. Two different sets of LEDs can be selected, either white LEDs or RGB LEDs. Four LP5521 Devices are assembled on one board to be able to evaluate the triggering/sequencing of multiple devices in one application.
