📥 Download Datasheet

General Description

The TLC5946 is a 16-channel, constant current sink LED driver.

Each channel is individually adjustable with 4096 pulse-width modulated (PWM) steps and 64 constant current sink steps for dot correction.

The dot correction adjusts the brightness variations between LEDs.
