Product details

Fixed 1.875V rail for low-power loads

The LM3674MF-1.875/NOPB is a step-down buck converter from Texas Instruments, delivering a fixed 1.875V output at up to 600mA from a 2.7V to 5.5V input rail. The 2MHz switching frequency lets the output filter use small ceramic capacitors and a compact inductor, shrinking the total footprint on a space-constrained board. The integrated synchronous rectifier eliminates the external Schottky diode, boosting efficiency at light loads and simplifying the BOM count.

Package and temperature grade

Housed in a 5-pin SOT-23-5 (SC-74A) surface-mount package, the part is supplied on Tape & Reel for pick-and-place assembly. Rated for operation from -30°C to 85°C ambient, it suits indoor and sheltered industrial environments where the board temperature stays within that window.

Lifecycle and compliance

Fully RoHS3 compliant, with no exemptions or lead-based finishes to track in your materials declaration.
