1.1 Introduction

The TLC6984 is a highly integrated, common cathode matrix LED display driver with 48 constant current sources and 16 scanning FETs. One TLC6984 is capable of driving 16 × 16 RGB LED pixels, while stacking two TLC6984s can drive 32 × 32 RGB LED pixels, three TLC6984s are capable of driving 48 × 48 RGB LED pixels, and stacking four TLC6984s can drive 64 × 64 RGB LED pixels. To achieve low power consumption, the device supports separated power supplies for the red, green, and blue LEDs by the common cathode structure. Furthermore, the operation power of the TLC6984 is significantly reduced by ultra-low operation voltage range (Vcc down to 2.5V) and ultra-low operation current (Icc down to 3.6mA).

This user’s guide describes the TLC6984 evaluation module used as a reference for engineering demonstration and evaluation. Included in this user’s guide are setup instructions, a schematic diagram, printed board (PCB) layout, and a bill of materials (BOM).
