Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | BS | passive | High-Side Gate Driver Bootstrap Supply. BS provides power to the gate driver of the internal n-channel MOSFET switch. Connect a 10nF or greater capacitor from SW to BS. Absolute max V_BS = V_SW - 0.3V to V_SW + 6V. |+| 2 | GND | power_in | Ground. This pin is the voltage reference for the regulated output voltage. It should be kept away from the D1 and input capacitor for noise prevention. |+| 3 | FB | input | Output Feedback Input. FB senses the output voltage to regulate that voltage. Connect FB to an external resistor divider to set the output voltage (V_FB typ = 0.8V). The value of the divider resistors also sets loop bandwidth. |+| 4 | EN | input | Enable Input. EN is a logic input that controls the regulator on or off. Drive EN logic high (>=1.5V) to turn on the regulator, and set EN logic low (<=0.4V) to turn it off. Don't leave EN floating. Directly connect EN to IN (or through a resistance) for automatic startup. |+| 5 | IN | power_in | Input Supply Pin. IN supplies the power to the IC and the power switch. Connect IN to a 4.5V to 30V power source. Bypass IN to GND with a suitably large value capacitor (e.g. 10µF) to minimize input ripple to the IC. |+| 6 | SW | output | Power Switcher Output. Connect the output LC filter from SW to the output. Switching node of the internal 0.3Ω N-channel DMOS; absolute max -1V to V_IN + 0.3V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Eutech Microelectronics |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `EUP3458VIR1`+- `EUP3458VIR1EUP3458OIR1`++## CAD (KiCad official)++- Symbol: `EUP3458VIR1`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-23-6 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Eutech Microelectronics datasheet](docs/eup3458vir1-datasheet.pdf) (11 pp, sha256 `6408ba23ca5d1258`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
