TPS61181RTET TI LED Driver | 16-WQFN (3x3) | 38V, 1.5A

Product Overview

The TPS61181RTET from Texas Instruments is a high-efficiency, step-up (boost) white LED driver designed for medium-sized LCD backlight applications. It integrates a 1.5A, 38V switch FET and supports up to 10 series LEDs. The device operates from a 2.7V to 18V input voltage range, making it suitable for single-cell Li-Ion or multi-cell alkaline/NiMH batteries. The TPS61181RTET features a 1.2MHz fixed switching frequency, which allows for small external components and reduces output ripple. It also includes PWM dimming control for precise brightness adjustment.
