LM3671MFX-2.8/NOPB TI Step-Down Converter | SOT-23-5 | 2.8V Output, 600mA

Product Overview

The LM3671MFX-2.8/NOPB is a high-efficiency, step-down DC-DC converter from Texas Instruments, designed to deliver a fixed output voltage of 2.8V with a maximum load current of 600mA. Housed in a compact SOT-23-5 package, this device is ideal for space-constrained applications requiring low power consumption and high efficiency. The LM3671 operates with an input voltage range of 2.7V to 5.5V, making it suitable for battery-powered systems and portable electronics. Its internal synchronous rectification and pulse-width modulation (PWM) control ensure excellent transient response and low output ripple.
