LP55281
Quad RGB Driver
General Description
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/I
2
C
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.
