TLC5947DAPR TI LED Driver | 32-HTSSOP | 24-Ch, 30mA, PWM

Product Overview

The TLC5947DAPR is a 24-channel, constant-current sink LED driver from Texas Instruments, designed for high-precision LED control. It features a 12-bit (4096-step) grayscale PWM control for each channel, enabling smooth and accurate brightness adjustments. The device operates with a supply voltage range of 3.0V to 5.5V and can sink up to 30mA per channel, making it suitable for a wide range of LED display and lighting applications. The TLC5947DAPR is housed in a 32-pin HTSSOP package with an exposed pad for enhanced thermal performance.
