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 | SOURCE | power_in | Source of the internal power MOSFET and reference ground for the control circuit. Pins 1 and 2 are tied together internally. |+| 2 | SOURCE | power_in | Source of the internal power MOSFET and reference ground for the control circuit. Pins 1 and 2 are tied together internally. |+| 3 | FB | input | Feedback current input. Input impedance ~1.15 kΩ. Shutdown current ~1 mA (0.8-1.3 mA); short-circuit protection triggers when IFB < 500 µA; frequency foldback between 830 µA and 930 µA. Maximum feedback current 3 mA. |+| 4 | VDD | power_in | Control-circuit supply. Operating range 10-25 V (after startup); startup threshold ~14.3 V, UVLO ~8.9 V, OVP ~28 V, clamp ~30 V, hiccup point ~10.7 V. Absolute max 30 V. |+| 5 | DRAIN | power_in | Drain of the internal high-voltage power MOSFET, also used for high-voltage startup current source. BVDSS ≥ 650 V, RDS(on) ~18 Ω, peak drain current 2.8 A pulsed / 0.8 A DC. Pins 5, 6, 7, 8 are tied together internally. |+| 6 | DRAIN | power_in | Drain of the internal high-voltage power MOSFET. Pins 5, 6, 7, 8 are tied together internally. |+| 7 | DRAIN | power_in | Drain of the internal high-voltage power MOSFET. Pins 5, 6, 7, 8 are tied together internally. |+| 8 | DRAIN | power_in | Drain of the internal high-voltage power MOSFET. Pins 5, 6, 7, 8 are tied together internally. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Hangzhou Silan Microelectronics |+| Package | SOP-8 |+| Category | PMIC |+| Pins | 8 |++## Ordering variants++- `SDH8302STRSDH8302S`+- `SDH8302STR`++## CAD (KiCad official)++- Symbol: `SDH8302STR`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Hangzhou Silan Microelectronics datasheet](docs/sdh8302str-datasheet.pdf) (9 pp, sha256 `fd90d6d09284280f`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
