3 Description

The LP55281 device is a quadruple RGB LED driver

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.
