TPS92411DDA TI LED Driver | 8-SO-POWERPAD | 100V, 1.5A

Product Overview

The TPS92411DDA is a high-voltage, floating buck LED driver from Texas Instruments, designed for high-brightness LED lighting applications. It operates from an input voltage range of 6V to 100V and delivers up to 1.5A of constant current to LEDs. The device features a unique floating buck topology that eliminates the need for an external sense resistor, reducing component count and solution size. With integrated high-side current sensing and a 200mV reference, it provides accurate LED current regulation. The TPS92411DDA is available in a thermally enhanced 8-pin SO PowerPad package, ensuring efficient heat dissipation.
