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.
For all available packages, see the orderable addendum at the
end of the data sheet.
