LP5009 Overview
In smart homes and other applications that use human-machine-interaction, high-performance RGB LED drivers are required. LED animation effects such as flashing, breathing and chasing that greatly improves user experience, and minimal system noise is essential. The LP50xx device is an 9- or 12-channel constant current sink LED driver.
