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 | A | passive | Anode terminal, equivalent to the anode of a rectifier diode in application. Internally tied to the source of the integrated 45V NMOS and used as the voltage reference point for all datasheet specs. Pins 1, 2, 3 are internally connected. |+| 2 | A | passive | Anode terminal (paralleled with pins 1 and 3). Connects to the source of the internal 45V/20mΩ NMOS rectifier. |+| 3 | A | passive | Anode terminal (paralleled with pins 1 and 2). Connects to the source of the internal 45V/20mΩ NMOS rectifier. |+| 4 | VCC | power_in | Chip supply pin. Startup threshold VCC_ON = 3.6V typ, UVLO VCC_OFF = 3.1V typ, normal operating range 5-6V. In 5V low-side applications VCC is tied directly to the output positive rail, so no external supply components are required. |+| 5 | K | passive | Cathode terminal, equivalent to the cathode of a rectifier diode. Internally tied to the drain of the 45V/20mΩ NMOS. Pins 5, 6, 7, 8 are internally connected and typically paralleled for current handling and heat dissipation. |+| 6 | K | passive | Cathode terminal (paralleled with pins 5, 7, 8). Connects to the drain of the internal 45V/20mΩ NMOS rectifier. |+| 7 | K | passive | Cathode terminal (paralleled with pins 5, 6, 8). Connects to the drain of the internal 45V/20mΩ NMOS rectifier. |+| 8 | K | passive | Cathode terminal (paralleled with pins 5, 6, 7). Connects to the drain of the internal 45V/20mΩ NMOS rectifier. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Shenzhen DongKe Semicon |+| Package | SOP-8 |+| Category | Power Management (PMIC) |+| Pins | 8 |++## CAD (KiCad official)++- Symbol: `DK5V45R20P`+- 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:** [Shenzhen DongKe Semicon datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8588914793289273344) (6 pp, sha256 `35b68995a142cde4`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
