TPS61140DRCT TI LED Driver | 10-VSON (3x3) | 2-Ch, 38V, 1.2A

Product Overview

The TPS61140DRCT from Texas Instruments is a highly integrated, dual-channel boost converter with current sinks designed for driving white LEDs in parallel or series configurations. It operates from a 2.5V to 6V input supply and can boost up to 38V, making it suitable for small to medium-sized LCD backlighting and general illumination applications. The device features two independent current sinks with programmable current up to 1.2A per channel, enabling flexible brightness control via PWM or analog dimming. Housed in a compact 10-pin VSON (3x3 mm) package, it offers a space-saving solution for portable electronics.
