TMI3408F

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.
