1.1 Introduction

This user’s guide describes the characteristics, setup, and usage of the LP5860T evaluation module (EVM). The LP5860TEVM helps the user evaluate the features of the Texas Instruments LP5860T high-current LED matrix driver, which integrates 11 scan switches and 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 a bill of materials,.

The LP5860TEVM is used to evaluate the characteristics, operation, and usage for LED matrix driver LP5860T. The LP5860T device is a high performance and small-size device, which integrates 18 constant current sinks with 11 switching MOSFETs, to drive up to 198 LED dots or 66 RGB LED pixels. 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 following topics:

The LP5860TEVM can be converted for testing the LP5868T and LP5866T, which are from the same device family, by removing the factory-installed device (U1) and replacing with the LP5868T or LP5866T counterpart. When testing the LP5868T or LP5866T device, select the corresponding tag from the menu on the GUI start page to start evaluation.
