LM3671TLX-3.3/NOPB TI Step-Down Converter | 5-DSBGA (1.41x1.08) | 3.3V Output, 600mA

Product Overview

The LM3671TLX-3.3/NOPB is a high-efficiency, step-down DC-DC converter from Texas Instruments, designed for portable and battery-powered applications. It delivers a fixed 3.3V output voltage with up to 600mA load current. Housed in a compact 5-DSBGA (1.41x1.08mm) package, it offers excellent power density and thermal performance. The device operates at a 2MHz fixed switching frequency, allowing the use of small external components. With a wide input voltage range of 2.7V to 5.5V, it is ideal for single-cell Li-Ion or multi-cell alkaline/NiMH powered systems.
