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 | GND | power_in | Chip ground. Tied together internally with pins 2 and 3. Used as the return for the internal control logic in the 'floating-ground' SR architecture. |+| 2 | GND | power_in | Chip ground. Tied together internally with pins 1 and 3. |+| 3 | GND | power_in | Chip ground. Tied together internally with pins 1 and 2. |+| 4 | VCC | power_in | Chip supply, nominally 5 V (abs-max 6 V, clamp ~6 V @ 20 mA). Bypass locally with ~1 µF. Fed by the internal HV LDO from SW, so no auxiliary winding is needed. UVLO(ON)=3.7 V, UVLO(OFF)=2.8 V. |+| 5 | SW | power_out | Drain of the internal synchronous-rectifier power MOSFET. Tied together internally with pins 6, 7 and 8 to carry the SR current. Absolute-max 65 V, recommended 4.7-60 V, 15 A continuous / 30 A pulsed. |+| 6 | SW | power_out | Drain of the internal SR power MOSFET (tied to pins 5, 7, 8). |+| 7 | SW | power_out | Drain of the internal SR power MOSFET (tied to pins 5, 6, 8). |+| 8 | SW | power_out | Drain of the internal SR power MOSFET (tied to pins 5, 6, 7). Also feeds the internal HV LDO that generates VCC. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HaloChip |+| Package | SOP-8 |+| Category | Power Management (PMIC) |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `GP7596B`+- `GP7596BA`+- `GP7596BB`+- `GP7596A`+- `GP7596AA`+- `GP7596AB`+- `GP7596C`+- `GP7596CA`+- `GP7596CB`++## CAD (KiCad official)++- Symbol: `GP7596B`+- 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:** [HaloChip datasheet](docs/gp7596b-datasheet.pdf) (7 pp, sha256 `c7e9e6914030b64f`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
