Small 36-bump Micro SMD (3 mm x 3 mm x 0.6 mm) or 36-bump Micro SMDxt package (3 mm x 3 mm x 0.65 mm)
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/I
2C 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.
