LP5012EVM User's Guide

This user’s guide describes the characteristics, setup, and use of the LP5012EVM evaluation module
(EVM). The LP5012EVM helps the user evaluate the features of the Texas Instruments LP5012 device,
which is an I

C bus-controlled, 12-channel, constant-current LED driver. This user’s guide includes setup

instructions, a schematic diagram, a bill of materials, printed-circuit board layout drawings, and software
instructions.

The LP5012EVM can be converted for testing the LP5009 device by removing the factory-installed device
(U1) and replacing it with the LP5009 counterpart. When testing the LP5009 device, select the
corresponding LP5009 tag from the menu on the GUI home page (

Figure 5

) for the evaluation.
