TLC5947DAP Description
The TLC5947DAP is a constant-current sink LED driver with 24 channels. Each channel has 4096 pulse-width modulated (PWM) steps that can be adjusted independently. With the programmed grayscale (GS) data, PWM control is automatically repeated. A serial interface port is used to write GS data. A single external resistor controls the current value of all 24 channels.
