LM3671TLX-1.875/NOPB TI Step-Down Converter | 5-DSBGA (1.41X1.08) | 1.875V Fixed Output, 600mA

Product Overview

The LM3671TLX-1.875/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 1.875V with a maximum load current of 600mA. Housed in a compact 5-DSBGA (1.41x1.08mm) package, it offers excellent power density and thermal performance. The device operates with an input voltage range of 2.7V to 5.5V, making it suitable for single-cell Li-Ion or multi-cell alkaline/NiMH batteries. Its high switching frequency (up to 2MHz) allows the use of small external components, reducing overall solution size.
