TLC5943PWPR TI LED Driver | 28-HTSSOP | 16-Channel, 12-Bit PWM

Product Overview

The TLC5943PWPR is a 16-channel, constant-current sink LED driver from Texas Instruments, designed for high-performance LED display and lighting applications. It features a 12-bit (4096-step) grayscale PWM control, enabling smooth and precise brightness adjustment. The device operates from a 3.0V to 5.5V supply voltage and provides a constant current range of 0.5 mA to 40 mA per channel, set by an external resistor. The TLC5943PWPR is housed in a compact 28-pin HTSSOP package with PowerPAD for enhanced thermal dissipation, making it suitable for space-constrained designs.
