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 pin for the high-side switch. Connect a 0.1μF (or larger) capacitor between BST and LX to supply gate drive for the top NMOS. Absolute max: −0.3V to LX+6V. |+| 2 | GND | power_in | Analog ground reference for the IC. Tie to the system ground plane and to the return of the input/output capacitors. |+| 3 | FB | input | Output feedback input. Senses the output voltage via an external resistive divider; regulated by the control loop to 795mV (typ). Absolute max: −0.3V to 6V. |+| 4 | EN | input | Enable input. Drive high (≥1.23V typ) to turn on the regulator, low (≤1.13V typ) to shut it down. May be tied directly to VIN. Absolute max: −0.3V to VIN+0.3V. IEN ≈ 4.4μA at 16V. |+| 5 | VIN | power_in | Input supply pin. Accepts 4.5V to 60V. Bypass to GND with a suitably large capacitor (typ. 10μF + 0.1μF) to eliminate input noise. |+| 6 | LX | power_out | Switching node output. Drain of the internal 850mΩ high-side NMOS. Connect the external inductor and catch diode here to feed the output LC filter. Absolute max: −0.3V to VIN+0.3V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | BL Shanghai Belling |+| Package | SOT-23-6L |+| Category | PMIC |+| Pins | 6 |++## CAD (KiCad official)++- Symbol: `BL9362`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-23-6L (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [BL Shanghai Belling datasheet](docs/bl9362-datasheet.pdf) (7 pp, sha256 `a7737ee5bd7c3cbe`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
