Description
General part information
TLC6946 Series
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.
The TLC694x device integrates enhanced circuits to solve the various display issues in fine-pitch LED display applications: the low-grayscale uniformity issue, coupling issue, ghosting issue, and caterpillar issue.
