TLC5947 24通道，12位PWM LED驱动器/控制器 Pdf资料

应用功能： 24通道，12位PWM LED驱动器/控制器 The TLC5947 is a 24-channel, constant current sink LED driver. Each channel is individually adjustable with 4096 pulse-width modulated (PWM) steps. PWM control is repeated automatically with the programmed grayscale (GS) data. GS data are written via a serial interface port. The current value of all 24 channels is set by a single external resistor.
