The LM3670MF-1.875/NOPB: Switching at a fixed 1 MHz, the internal synchronous rectifier keeps external component count low — a single inductor and two capacitors are typically enough for a clean output.
It is a step-down (buck) DC-DC converter with a fixed 1.875 V output, synchronous rectification, and 350 mA current capability, switching at 1 MHz.
