LM3671QMF-1.2/NOPB TI Step-Down Converter | SOT-23-5 | 1.2V Fixed Output, 600mA

Product Overview

The LM3671QMF-1.2/NOPB is a high-efficiency, step-down DC-DC converter from Texas Instruments, designed to deliver a fixed 1.2V output from a 2.7V to 5.5V input supply. Housed in a compact SOT-23-5 package, this device is capable of supplying up to 600mA of load current. Its synchronous rectification topology ensures high efficiency over a wide load range, making it ideal for battery-powered and space-constrained applications. The device features automatic PFM/PWM mode switching to optimize efficiency at light loads, and includes built-in over-current and thermal shutdown protection.
