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 | GND | power_in | Ground return for the device. Connect to the system ground plane with low-impedance path close to the input capacitor. |+| 2 | SW | output | Switching node. Connect the external power inductor between SW and the regulator output. Internally driven by the high-side and low-side power MOSFETs (RDS(on) ~37mΩ HS / ~25mΩ LS). |+| 3 | VIN | power_in | Supply input, 2.5V to 5.5V. Bypass with a 22µF ceramic capacitor to GND placed close to the pin. Absolute maximum 7V. |+| 4 | EN | input | Enable input. Drive high (rising threshold typ 1.2V, falling 0.4V) to enable the converter; drive low to shut down (IQ <1µA). For automatic start-up, tie EN to VIN through a pull-up resistor. Absolute maximum 7V. |+| 5 | FB | input | Feedback input to the internal error comparator. Connect an external resistor divider from VOUT to FB and GND to set the output voltage: VOUT = 0.6V × (1 + R1/R2). Internal reference 0.6V (±1%); R2 should be 1kΩ-70kΩ. |+| 6 | OUT | input | Output sense/feed-forward pin. Connect to VOUT (the regulated output rail) or leave not connected. Used internally by the Adaptive COT control loop. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | etasolution |+| Package | SOT-563 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `ETA3458FSGFSG`++## CAD (KiCad official)++- Symbol: `ETA3458FSG`+- Footprint: `Package_TO_SOT_SMD:SOT-563`+- 3D model: SOT-563 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [etasolution datasheet](docs/eta3458fsg-datasheet.pdf) (10 pp, sha256 `842e4e68b2a492eb`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
