TPS61040QDBVRQ1 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 | SW | output | Switch pin connected to the drain of the internal power MOSFET; connect the inductor and Schottky diode to this pin. |
| 2 | GND | power_in | Ground |
| 3 | FB | input | Feedback pin; connect to the external voltage divider to program the desired output voltage. |
| 4 | EN | input | Enable pin; pulling this pin to ground forces the device into shutdown mode reducing the supply current to less than 1 µA; must not be left floating and must be terminated. |
| 5 | VIN | power_in | Supply voltage pin |
