9 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
9.1 Application Information
The LP50xx device is a 9- or 12-channel constant-current-sink LED driver. The LP50xx device improves the user
experience in color mixing and intensity control, for both live effects and coding effort. The optimized
performance for RGB LEDs makes it a good choice for human-machine interaction applications.
9.2 Typical Application
The LP50xx design supports up to four devices in parallel with different configurations on the ADDR0 and
ADDR1 pins.
