TLC5941EVM-105 EVM
This user’s guide describes the characteristics, operation, and use of the
TLC5941EVM-105 evaluation module (EVM). This EVM is designed to help the user
evaluate and test the various operating modes of the TLC5941. This user’s guide
includes setup instructions for the hardware and software, a schematic diagram, a bill
of materials (BOM), and PCB layout drawings for the evaluation module

The Texas Instruments TLC5941 is a 16 channel, constant-current LED driver that is capable of driving
80mA per channel. The IC contains an integrated DOT correction circuitry that adjusts the dc current for
each output channel to compensate for brightness difference between LEDs. It also has integrated PWM
grayscale control to provide individual LED dimming.
This EVM contains three TLC5941 ICs that are connected in series. The three TLC5941 ICs drive 16
red-green-blue light emitting diodes (RGB LEDs). Each TLC5941 drives a separate color. Each TLC5941
has 16 outputs and each output is connected to a different LED. Using the software, the user individually
controls the DOT correction and grayscale values for each color of each LED.
