1.1 Introduction

This user’s guide describes the characteristics, setup, and usage of the LP5861T evaluation module (EVM). The LP5861TEVM helps the user evaluate the features of the Texas Instruments LP5861T LED linear driver, which integrates 18 constant current sinks. This user’s guide includes hardware setup instructions, graphical user interface (GUI) instructions, printed-circuit board (PCB) layout drawings, a schematic diagram, and the bill of materials.

The LP5861TEVM is used to evaluate the characteristics, operation, and usage for LED linear driver LP5861T. The LP5861T device is a high performance and small-size device, which integrates 18 constant current sinks to drive up to 18 LED dots or 6 RGB LEDs. Every LED dot is supported by 8-bit analog dimming and 8-bits or 16-bits configurable PWM dimming methods, which enable smooth and audible-noise-free dimming control.

This document covers the following topics:

The LP5861TEVM can be converted for testing the LP5861, which are from the same device family, by removing the factory-installed device (U1) and replacing with the LP5861 counterpart. When testing the LP5861 device, select the corresponding tag from the menu on the GUI start page to start evaluation.
