TLC6946 Evaluation Module
1 Introduction
1.1 Features
The TLC6946 device is a 16-channel, constant-current-sink LED driver. Each channel has an individually-
adjustable 65 536 steps of PWM grayscale control. The maximum constant-current value of all 16
channels is set by a single external resistor with 7-bit (128 steps) global brightness control from 0.3 mA to
25 mA. The BOOSTXL-TLC6946EVM uses three TLC6946 devices to drive 16 RGB LEDs, each device
controlling one color. Moreover, the EVM provides the function to verify the LED-Open Detection (LOD)
and IREF Resistor Short Protection (ISP).
1.2 Applications
The BOOSTXL-TLC6946EVM can be used as a basic function evaluation module for the following
applications:
• Mono-color, multi-color, full-color LED displays
• High-refresh-rate LED video displays
• High-density, fine-pitch LED matrix boards
• LED sign boards, message boards
• Variable message signs (VMS)
