TLC5947 - 24-Channel 12-Bit PWM LED Driver

Description

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.

Features

  • 30-mA Capability (Constant-Current Sink).
  • 12-Bit (4096 Steps) PWM Grayscale Control.
  • LED Power-Supply Voltage Up to 30 V.
  • VCC = 3.0 V to 5.5 V.
  • Constant-Current Accuracy:.
  • Channel-to-Channel = ±2% (Typical).
  • Device-to-Device = ±2% (Typical).
  • CMOS Logic Level I/O.
  • 30-MHz Data Transfer Rate (Standalone).
  • 15-MHz Data Transfer Rate (Cascaded Devices, SCLK Du.
