The LP3931 is a RGB LED driver with high current boost DC-DC converter designed for portable wireless applica- tions. It contains 2 sets of RGB LED drivers that are PWM- driven with programmable color, intensity and blinking pat- terns. They additionally feature a FLASH function to support picture taking with camera-enabled cellular phones. An efficient magnetic boost DC/DC converter provides the required bias, operating from a single Li-Ion battery. The DC/DC converter output voltage is user programmable for adapting to different LED types and for efficiency optimiza- tion. All functions are software controllable through the SPI inter- face and internal registers.
