1 Introduction

The LP5860EVM is used to evaluate the characteristics, operation, and usage for LED matrix driver LP5860.
The LP5860 device is a high performance and small size solution, 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:

•

How to set up the LP5860EVM hardware

•

How to use the LP5860 GUI to illuminate LEDs

•

Design resources for the LP5860EVM

The LP5860EVM kit includes the following materials and is illustrated in

.

• LP5860 evaluation module
• USB2ANY interface adapter with ribbon cables and USB cable

Full functions for the LP5860, the performance with RGB LED matrix, and some simple animation effects can be
easily verified through this kit.

The LP5860EVM can be converted for testing the LP5868 and LP5866, which are from the same device family,
by removing the factory-installed device (U1) and replacing it with the LP5868 or LP5866 counterpart. When
testing the LP5868 or LP5866 device, select the corresponding tag from the menu on the GUI start page to start
evaluation.
