TLC5947RHBT TI LED Driver | 32-VQFN (5x5) | 24-Ch, 30mA, PWM

Product Overview

The TLC5947RHBT is a 24-channel, constant-current sink LED driver from Texas Instruments, designed for high-precision LED control in a compact 32-VQFN (5x5 mm) package. It integrates a 12-bit PWM grayscale control and a 6-bit global brightness adjustment, enabling smooth and accurate LED dimming. With a maximum output current of 30 mA per channel, it is ideal for applications requiring high-resolution color mixing and uniform brightness, such as LED displays, signage, and automotive lighting.
