TPS61041DBVRG from HANSCHIP semiconductor, 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 node connected to the drain of the internal power MOSFET, where the inductor and Schottky diode connect; the datasheet lists the maximum switch voltage as 30 V. |
| 2 | GND | power_in | Ground reference pin for the device. |
| 3 | FB | input | Feedback pin that connects to the external voltage divider to set the output voltage, with VOUT = 1.233 V × (1 + R1/R2) and EN and FB rated to VIN + 0.3 V maximum. |
| 4 | EN | input | Enable pin; pulling it to ground forces shutdown with supply current below 1 µA, and it must not be left floating and needs to be terminated. |
| 5 | VIN | power_in | Supply voltage pin with an input voltage range of 1.8 V to 6 V. |
