TLC5929DBQ TI LED Driver | 24-SSOP | 16-Channel, Constant Current

Product Overview

The TLC5929DBQ is a 16-channel constant-current sink LED driver from Texas Instruments, designed for high-performance display and lighting applications. It integrates a shift register, data latch, and constant-current output stages, enabling precise control of LED brightness and color. The device operates from a 3V to 5.5V supply and supports a maximum output current of 120 mA per channel, with global brightness control via an external resistor. Its 24-pin SSOP package offers a compact solution for space-constrained designs.
