LM3679URX-1.8/NOPB TI Step-Down Converter | 5-DSBGA (1.47x1.02) | 1.8V Fixed Output, 600mA

Product Overview

The LM3679URX-1.8/NOPB is a high-efficiency, 600mA step-down DC-DC converter from Texas Instruments, designed for battery-powered and portable applications. It provides a fixed 1.8V output from an input voltage range of 2.5V to 5.5V, making it ideal for powering low-voltage digital cores, I/O, and memory. Housed in a compact 5-DSBGA package (1.47mm x 1.02mm), it minimizes board space while delivering excellent transient response and low ripple.
