LP3950  
Color LED Driver with Audio Synchronizer  
General Description  
Features  
n Audio synchronization for color LEDs with two modes:  
Amplitude and Frequency  
The LP3950 is a color LED driver with a built-in audio  
synchronization feature for any analog audio input such as  
polyphonic ring tones and MP3 music. LEDs can be syn-  
chronized to an audio signal with two methods - amplitude  
and frequency. Also several fine tuning options are available  
for differentiation purposes. The chip also has an unique  
AGC (Automatic Gain Control) feature which tracks the input  
signal level and automatically adjusts the gain to an optimal  
value.  
n Programmable frequency and amplitude response with  
tracking speed control  
n Automatic gain control or selectable gain for input signal  
optimization  
n RGB pattern generator similar to LP3933/LP3936  
n
Magnetic DC-DC boost converter with programmable  
boost output voltage  
n Selectable SPI or I2C compatible interface  
n One pin default enable for non-serial interface users.  
One pin selector for synchronization mode  
The LP3950 has a high efficiency magnetic DC/DC con-  
verter with programmable output voltage and switching fre-  
quency. The converter has high output current capability so it  
is also able to drive flash LEDs in camera phone applica-  
tions.  
n Space efficient 32-pin thin CSP laminate package  
The LP3950 is similar to LP3933 and LP3936 in that the  
color LEDs (or RGB LEDs) can also be programmed to  
generate light patterns (programmable color, intensity, on/off  
timing, slope and blinking cycle).  
All functions are software controllable through a SPI or I2C  
compatible interface but the device also supports one pin  
control for enabling predefined (default) audio synchroniza-  
tion mode.  
Applications  
n Cellular phones  
n MP3/CD/minidisc players  
n Toys
