TLC5954RTQT TI LED Driver | 56-QFN (8x8) | 48-Channel, 16-Bit PWM

Product Overview

The TLC5954RTQT is a 48-channel constant-current sink LED driver from Texas Instruments, designed for high-performance display and lighting applications. It integrates a 16-bit PWM grayscale control with an internal shift register and latch, enabling precise brightness and color mixing. The device operates from a 3.0V to 5.5V supply and provides a constant current range of 0.5 mA to 35 mA per channel, adjustable via an external resistor. The 56-QFN (8x8 mm) package offers a compact footprint for space-constrained designs.
