3 Description
In high-density, fine-pitch LED panel applications, the
performance demand for multi-channel LED drivers is
increasing to achieve high multiplexing, high PWM
resolution, and high refresh rates. To meet strict
display quality requirements, the LED drivers must
have the ability to solve various issues in different
LED-matrix application scenarios.
The TLC694x 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 128 steps of global brightness control
from 0.3 mA to 25 mA.
