LP55281
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 synchronize 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 ponents 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.
