LM3670MFX-ADJ

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

LM3670MFX-ADJ 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, connected to the input filter capacitor; recommended input voltage range is 2.5 V to 5.5 V.
2 GND power_in Ground pin.
3 EN input Digital enable input; pulling EN low puts the device in shutdown, where it draws 0.1 µA typical.
4 FB input Analog feedback input, connected to the output filter capacitor; on the adjustable version it sets the output voltage (0.7 V to 2.5 V).
5 SW output Switching node connecting the internal PFET switch and NFET synchronous rectifier to the inductor; the inductor saturation current rating must exceed the 750-mA maximum switch peak current limit.
