TPS611781RNWR TI LED Driver | 13-VQFN-HR(3x3.5) | 2.5-5.5V Input, 1.5A Switch

Product Overview

The TPS611781RNWR from Texas Instruments is a high-efficiency, synchronous boost converter with an integrated 1.5A switch, designed to drive up to 10 series white LEDs or provide a regulated output voltage up to 24V. It operates from an input voltage range of 2.5V to 5.5V, making it ideal for battery-powered applications. The device features a 1.2MHz fixed switching frequency, which allows for small external components and reduces output ripple. The TPS611781RNWR is available in a compact 13-pin VQFN-HR package (3mm x 3.5mm) with a 0.5mm pitch, suitable for space-constrained designs.
