TMI · DC-DC Converters · SOT-23-5
TMI3408F from TMI, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | EN | input | Chip Enable Pin; drive above 1.5V to turn on the device, below 0.3V to turn it off, do not leave floating. |
| 2 | GND | power_in | Ground Pin. |
| 3 | LX | output | Power Switch Output node connection to Inductor; voltage range -0.3V to 6.5V. |
| 4 | VIN | power_in | Power Supply Input (2.5V to 5.5V); must be closely decoupled to GND with 4.7µF or greater ceramic capacitor. |
| 5 | FB | input | Output Voltage Feedback Pin with regulated feedback voltage 0.588V to 0.612V at 25°C. |
