TPS5410D from Texas Instruments, in a SOIC-8. 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 | BOOT | output | Boost capacitor for the high-side FET gate driver; connect a 0.01 μF low ESR capacitor from the BOOT pin to the PH pin. |
| 2 | NC | unconnected | Not connected internally. |
| 3 | NC | unconnected | Not connected internally. |
| 4 | VSENSE | input | Feedback voltage for the regulator; connect to the output voltage divider. |
| 5 | ENA | input | On and off control; below 0.5 V the device stops switching, and the pin is floated to enable the device. |
| 6 | GND | power_in | Ground. |
| 7 | VIN | power_in | Input supply voltage; bypass the VIN pin to the GND pin close to the package with a high quality, low ESR ceramic capacitor. |
| 8 | PH | output | Source of the high side power MOSFET, connected to the external inductor and diode. |
