TPS5420MDREP 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 0.01-µF low-ESR capacitor between BOOT pin and PH pin. |
| 2 | NC | unconnected | Not connected internally. |
| 3 | NC | unconnected | Not connected internally. |
| 4 | VSENSE | input | Feedback voltage for the regulator; connect to output voltage divider. |
| 5 | ENA | input | On/off control; device stops switching below 0.5 V; float the pin to enable. |
| 6 | GND | power_in | Ground. |
| 7 | VIN | power_in | Input supply voltage (5.5 V to 35 V); bypass to GND with high-quality low-ESR ceramic capacitor. |
| 8 | PH | output | Source of the high-side power MOSFET; connected to external inductor and diode. |
