LP3952 6-Channel Color LED Driver with Audio Synchronization www.DataSheet4U.com July 2007 LP3952 6-Channel Color LED Driver with Audio Synchronization General Description LP3952 is a color LED driver for battery powered handheld devices. It drives any color LEDs including RGB LEDs, indicator LEDs and keypad backlight LEDs. The boost DC-DC converter drives high current loads with high efficiency. The stand-alone command based RGB controller is feature rich and easy to configure. Different lighting patterns and blinking sequences can be programmed to driver registers. Built-in audio synchronization feature allows user to synchronize the color LEDs to audio signal. LED lighting can be controlled either by audio signal amplitude or frequency.
