TLC5945PWPR TI LED Driver | 28-HTSSOP | 16-Channel, Constant Current

Product Overview

The TLC5945PWPR is a 16-channel, constant-current sink LED driver from Texas Instruments (TI), designed for high-performance 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 adjustable output current up to 120 mA per channel via an external resistor. Its 28-pin HTSSOP package offers a compact footprint for space-constrained designs.
