Texas Instruments LP5562 | Demoboard LP5562EVM

Description

The LP5562 is a four channel LED driver designed to produce a variety of lighting effects for mobile devices. The device has a program memory for creating variety of lighting sequences. When program memory has been loaded, the LP5562 can operate independently without processor controlThe LP5562EVM Evaluation Kit is based on a computer controlled system, where the actual LP5562 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.
