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 | Boot-strap pin. Supplies the high-side gate driver. Decouple this pin to LX with a 0.1uF ceramic capacitor. |+| 2 | GND | power_in | Ground pin. Common return for power and signal. |+| 3 | FB | input | Output feedback pin. Connect to the center of the output resistor divider to program the output voltage: Vout = 0.6V × (1 + R1/R2). Internal reference 0.6V ±1.5%. |+| 4 | EN | input | Enable control input. Pull high (>1.5V rising threshold) to turn the regulator on; below 0.4V it is off. Do not float. |+| 5 | IN | power_in | Input supply pin, 4.5V to 23V. Decouple to GND with at least a 1uF ceramic capacitor placed close to the pin. |+| 6 | LX | power_out | Switching node. Connect to the external inductor. Internal top/bottom FETs switch this node at 500 kHz with 3A output capability. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Silergy Corp |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `SY8253ADCADC`+- `SY8253ADCAIC`++## CAD (KiCad official)++- Symbol: `SY8253ADC`+- 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:** [Silergy Corp datasheet](docs/sy8253adc-datasheet.pdf) (13 pp, sha256 `a5a2858a74928804`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
