LM3671TL-2.8/NOPB TI DC-DC Converter | 5-DSBGA (1.41X1.08) | 2.8V Output, 600mA

Product Overview

The LM3671TL-2.8/NOPB is a high-efficiency, step-down DC-DC converter from Texas Instruments, designed to deliver a fixed 2.8V output from a single Li-Ion or 3-cell NiMH/NiCd battery input. Housed in a compact 5-DSBGA (1.41x1.08 mm) package, it provides up to 600mA of output current with excellent load and line regulation. The device operates at a fixed 2 MHz switching frequency, allowing the use of small external components while maintaining high efficiency across the load range. With integrated power switches, soft-start, and thermal shutdown, the LM3671TL-2.8/NOPB is ideal for space-constrained, battery-powered applications.
