TLC5955RTQT TI LED Driver | 56-QFN (8x8) | 48-Channel, 16-Bit PWM

Product Overview

The TLC5955RTQT is a 48-channel, constant-current sink LED driver from Texas Instruments (TI), designed for high-performance display and lighting applications. It integrates a 16-bit (65,536 levels) PWM grayscale control with a 7-bit global brightness adjustment, enabling precise and smooth LED dimming. The device operates from a 3.0V to 5.5V supply and features a serial interface for data communication. Housed in a compact 56-pin QFN (8x8 mm) package, it is ideal for space-constrained designs requiring high channel density.
