TPS62208DBVR 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 | VI | power_in | Supply voltage pin; the recommended supply range is 2.5 V to 6 V. |
| 2 | GND | power_in | Ground reference pin for the device. |
| 3 | EN | input | Enable pin: pulling it to ground forces shutdown mode and pulling it to VIN enables the device; it must not be left floating and must be terminated. |
| 4 | FB | input | Feedback pin: connect directly to the output for the fixed-output-voltage version, or connect an external resistor divider to it for the adjustable version, where the internal voltage divider is disabled. |
| 5 | SW | bidirectional | Switch pin (datasheet type I/O): connect the inductor to this pin, which is connected to the internal MOSFET switches. |
