TMI3101D

TMI · DC-DC Converters · DFN-6-EP(2x2)

TMI3101D from TMI, in a DFN-6-EP(2x2). 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 LX output Power switch output that is the switch node connection to the inductor.
2 NC unconnected Not connected.
3 FB input Output voltage feedback pin, regulated to 0.600V typical reference.
4 EN input Chip enable pin: drive above 1.5V to turn on the part, below 0.3V to turn it off, and do not leave it floating.
5 VIN power_in Power supply input (2.5V to 6.0V operating range) that must be closely decoupled to GND with a 10µF or greater ceramic capacitor.
6 GND power_in Ground pin.
EP GND power_in Exposed pad connected to GND, shown in the package top view as GND.
