TLC59731DR TI LED Driver | 8-SOIC | 3-Channel, Constant Current

Product Overview

The TLC59731DR from Texas Instruments is a 3-channel, constant-current LED driver designed for precise control of RGB or single-color LEDs. It features a 3-wire serial interface (SDI, SCLK, LATCH) for daisy-chaining multiple devices, making it ideal for applications requiring high channel counts. The device operates from a supply voltage of 3V to 5.5V and provides adjustable constant current up to 60 mA per channel via an external resistor. The TLC59731DR is available in an 8-pin SOIC package, offering a compact solution for space-constrained designs.
