Description
General part information
LP55281 Series
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.
