**TECH PUBLIC** · DC-DC Converters · SOT-23-5

TPS61040DBVR-TP from TECH PUBLIC, 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 | passive | Switch pin connected to the internal MOSFET switches and inductor terminal; connect the inductor to this pin (absolute max -0.3 V to 35 V). |
| 2 | GND | power_in | Analog ground pin. |
| 3 | FB | input | Feedback pin, voltage range -0.3 V to VIN (internal reference 1.233 V). |
| 4 | EN | input | Enable pin, voltage range -0.3 V to VIN. |
| 5 | VIN | power_in | Supply voltage pin, recommended 2.7 V to 5.5 V (absolute max 7.0 V). |
