# TPS5410MDREP

**Texas Instruments** · DC-DC Converters · SOIC-8

TPS5410MDREP 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 | passive | 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 input for the regulator; connect to the output voltage divider, with steady-state VSENSE equal to the 1.221 V voltage reference. |
| 5 | ENA | input | On/off control; below 0.5 V the device stops switching, and the pin can be floated to enable the device because it has an internal pullup current source. |
| 6 | GND | power_in | Ground. |
| 7 | VIN | power_in | Input supply voltage, 5.5 V to 36 V recommended operating range; bypass to GND 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 catch diode; steady-state absolute maximum rating is -0.6 V to 40 V. |
