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 | BST | passive | Bootstrap. Positive supply for the internal floating high-side MOSFET driver. Connect a bypass capacitor between this pin and SW. BST-to-SW absolute max is 6.0V. |+| 2 | GND | power_in | Ground return. Should be routed as close as possible to the output capacitor and kept away from high-current switching paths. |+| 3 | FB | input | Feedback input. Sets output voltage via an external resistor divider from VOUT to GND. Internal reference is 0.812V (typ). A frequency-foldback comparator lowers switching frequency (to ~150kHz) when FB < 250mV to prevent current-limit runaway during short-circuit. |+| 4 | EN | input | Enable input. Pull above VENR (1.35V typ) to enable; pull below VENF (1.17V typ) to disable. A 100kΩ pull-up to IN allows automatic turn-on. Absolute max 6.0V. |+| 5 | VIN | power_in | Input supply, 4.5V to 60V operating (absolute max 62V). Powers all internal control circuits. Requires a decoupling capacitor to ground placed close to this pin to reduce switching spikes. |+| 6 | SW | output | Switch output. Drain of the internal high-side MOSFET (RDS(on) ≈ 1Ω). Connect the external inductor and catch Schottky diode here. Voltage range -0.3V to VIN(MAX)+0.3V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Shanghai Siproin Microelectronics |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## CAD (KiCad official)++- Symbol: `SSP9459`+- 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:** [Shanghai Siproin Microelectronics datasheet](docs/ssp9459-datasheet.pdf) (8 pp, sha256 `40202436a30fcb96`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
