Product Information

Description

The Texas Instruments TLC5940 is a 16 channel constant current LED driver that is capable of driving 120 mA 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. DOT correction information can be written into a non-volatile EEPROM or into internal registers. It also has integrated PWM grayscale control to provide individual LED dimming.

This EVM contains three TLC5940 ICs that are connected in series. The three TLC5940 ICs drive 16 red-green-blue light emitting diodes (RGB LEDs). Each TLC5940 drives a separate color. Each TLC5940 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.
