TLC5957 Overview
The TLC5957 is a 48-channel constant current sink driver. Each channel has an individually-adjustable, 65536-step, pulse width modulation (PWM) grayscale (GS) brightness control. The output channels are divided into three groups, each group has a 512 step color brightness control (CC), CC adjusts brightness between colors.
