TLC5941PWPR TI LED Driver | 28-HTSSOP | 16-Ch, 120mA, PWM Dimming

Product Overview

The TLC5941PWPR is a 16-channel, constant-current sink LED driver from Texas Instruments, designed for high-performance LED display and lighting applications. It integrates a 16-bit shift register, data latches, and constant-current output stages, enabling precise control of LED brightness and color mixing. The device operates from a 3.0V to 5.5V supply and provides a maximum output current of 120 mA per channel, adjustable via an external resistor. With a 30 MHz data transfer rate and 16-bit grayscale control, it is ideal for applications requiring high-resolution PWM dimming.
