LM3670MFX-1.8/NOPB TI DC-DC Converter | SOT-23-5 | 1.8V Output, 350mA

Product Overview

The LM3670MFX-1.8/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 1.8V with a maximum load current of 350mA. Housed in a compact SOT-23-5 package, this device integrates a synchronous rectifier for improved efficiency, reducing external component count. The LM3670 operates at a fixed switching frequency of 2MHz, allowing the use of small inductors and capacitors, making it ideal for space-constrained designs.
