TLC69651RTWR TI LED Driver | 24-WQFN (4x4) | 48-Ch, 5.5V, PWM Dimming

Product Overview

The TLC69651RTWR is a 48-channel constant-current LED driver from Texas Instruments, designed for high-resolution local dimming in display backlighting and direct LED lighting applications. It integrates a 5.5V supply, 16-bit PWM dimming, and a 3-wire serial interface, enabling precise brightness control with minimal external components. The compact 24-WQFN (4x4 mm) package makes it ideal for space-constrained designs.
