LM3670MF-1.8

Texas Instruments · DC-DC Converters · SOT-23-5

LM3670MF-1.8 from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN power_in Power supply input that connects to the input filter capacitor in the fixed-output typical application.
2 GND power_in Ground pin.
3 EN input Digital enable input; the datasheet's pin table gives no logic threshold, and the device enters shutdown when EN is pulled low.
4 FB input Analog feedback input that connects to the output filter capacitor in the fixed-output typical application.
5 SW output Switching node connected to the internal PFET switch and NFET synchronous rectifier; the connected inductor's saturation current rating must exceed the 750-mA maximum switch peak current limit.

CAD (KiCad official)

  • Symbol: LM3670MF-1.8
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: lm3670mf-1-8-etched.step / lm3670mf-1-8-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm3670mf-1-8.step / lm3670mf-1-8.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
