LP55281 12-Channel RGB/White-LED Drive With SPI, I2C Interface  
1 Features  
3 Description  
The LP55281 device is a quadruple RGB LED driver  
1
Audio Synchronization for a Single Fun-Light LED  
Four PWM Controlled RGB LED Drivers  
High-Efficiency Boost DC-DC Converter  
SPI or I2C-Compatible Interface  
for handheld devices. It can drive 4 RGB LED sets  
and a single fun-light LED. The boost DC-DC  
converter drives high current loads with high  
efficiency. The RGB driver can drive individual color  
LEDs or RGB LEDs powered from boost output or  
external supply. Built-in audio synchronization feature  
allows user to synchronize the fun-light LED to audio  
inputs. The flexible SPI or I2C interface allows easy  
control of LP55281. A small YZR0036 or YPG0036  
package, together with minimum number of external  
components, is a best fit for handheld devices. The  
LP55281 also has an LED test feature, which can be  
used, for example, in production for checking the LED  
connections.  
Two Addresses in I2C-Compatible Interface
