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. |
