TPS62273DRVR from Texas Instruments, in a WSON-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 | SW | output | Switch pin connected to the internal MOSFET switches; the inductor connects to this terminal. |
| 2 | VSEL | input | Voltage select input that chooses between the two fixed output voltages in the ordering table; the datasheet gives VIH of 1 V to VIN and VIL of 0 to 0.4 V for 2 V ≤ VIN ≤ 6 V. |
| 3 | FB | input | Feedback pin for the internal regulation loop; connect the external resistor divider here, or connect it directly to the output capacitor in the fixed-output-voltage option. |
| 4 | EN | input | Enable pin: pulling it low forces shutdown and pulling it high enables the device, with VIH of 1 V to VIN and VIL of 0 to 0.4 V, and the pin must be terminated. |
| 5 | VIN | power_in | VIN power supply pin; the recommended supply voltage range is 2 V to 6 V. |
| 6 | GND | power_in | GND supply pin, which the layout guidance says should be connected to the PowerPad used as the star point. |
| 7 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
