TLC5970 Datasheet (Texas Instruments) - 3-Channel 12-Bit PWM LED Driver

TLC5970, 3-Channel 12-Bit PWM LED Driver

The TLC5970 is a three-channel, constant-current sink driver with a buck dc/dc converter and a differential signal interface.

Each channel has individually adjustable currents with 4096 PWM grayscale (GS) steps and 128 constant-current sink steps for dot correction (DC).

The dot correction adjusts t
