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, indi-
cator 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 ei-
ther by audio signal amplitude or frequency. There are many
controls available for audio synchronization to get desired
lighting effect, including gain, speed, and different filter set-
tings. The flexible I
2
C interface allows easy control of LP3952.
LED outputs can be also controlled with external PWM signal.
Small micro SMDxt package together with minimum number
of external components is a best fit for handheld devices.
