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. There are many
controls available for audio synchronization to get desired
lighting effect, including gain, speed, and different filter settings.
The flexible I2C 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.
