TLC5940PWPR TI LED Driver | 28-HTSSOP | 16-Channel, Constant Current

Product Overview

The TLC5940PWPR is a 16-channel constant-current sink LED driver from Texas Instruments (TI), designed for high-performance LED control in applications requiring precise current regulation and grayscale control. Housed in a compact 28-HTSSOP package, it integrates a 16-bit shift register, data latches, and constant-current output stages. Each channel can be independently adjusted via serial interface, enabling smooth PWM dimming and pattern generation. The device operates over a wide supply voltage range (3.0V to 5.5V) and supports output currents up to 120 mA per channel, making it suitable for both low-power and medium-power LED arrays.
