  • LED Connectivity Test Through the Serial Interface

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.
