LM3671MFX-2.5/NOPB TI DC-DC Converter | SOT-23-5 | 2.5V Output, 600mA

Product Overview

The LM3671MFX-2.5/NOPB is a high-efficiency, step-down DC-DC converter from Texas Instruments, designed for portable and battery-powered applications. It delivers a fixed output voltage of 2.5V with a load capability up to 600mA. Housed in a compact SOT-23-5 package, this device integrates a synchronous rectifier for improved efficiency, reducing external component count. With a wide input voltage range of 2.7V to 5.5V, it is ideal for systems powered by single-cell Li-Ion batteries or 3.3V/5V rails. The device features automatic PFM/PWM mode switching to maintain high efficiency across the load range, and includes internal soft-start, current limit, and thermal shutdown protection.
