TPS6282518DMQR from Texas Instruments, in a VSON-6(1.5x1.5). 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 | EN | input | Device enable pin that must be pulled high to enable the device, pulling it low disables the device, and it must not be left floating. |
| 2 | PG | output | Power-good open-drain output whose pullup resistor can be connected to voltages up to 5.5V, and which may be left floating if unused. |
| 3 | FB | input | Feedback pin that must be connected to the output for the fixed output voltage versions. |
| 4 | GND | power_in | Ground pin. |
| 5 | SW | power_out | Switch pin of the power stage. |
| 6 | VIN | power_in | Input voltage pin; for the TPS62825x and TPS62826x family the input voltage range is 2.4V to 5.5V. |
