TLC5948A Description
The TLC5948A is a 16-channel, constant-current sink LED driver. Each channel has an individuallyadjustable, pulse width modulation (PWM) grayscale (GS) brightness control with 65,536 steps and 128 steps of constant-current dot correction (DC). DC adjusts brightness deviation between channels.
