LP55281

Quad RGB Driver

General Description

Features

LP55281 is a quad 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 synchro-

nize the fun light LED to audio inputs. The flexible SPI/I²C

interface allows easy control of LP55281. Small Micro SMD

or Micro SMDxt package together with minimum number of

external components is a best fit for handheld devices.

LP55281 has also a LED test feature, which can be used for

example in production for checking the LED connections.
