TLC5940PWP TI LED Driver | 28-HTSSOP | 16-Ch, Dot Correction, Grayscale PWM

Product Overview

The TLC5940PWP is a 16-channel, constant-current sink LED driver from Texas Instruments, designed for applications requiring high-precision current control and grayscale PWM dimming. Each channel features individual dot correction (6-bit) and grayscale control (12-bit), enabling accurate brightness adjustment and color mixing. The device operates from a 3.0V to 5.5V supply and supports a maximum output current of 120 mA per channel, configurable via an external resistor. The 28-pin HTSSOP package offers a compact footprint with exposed pad for thermal dissipation.
