NDP7931AKC from NDP, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground pin; the datasheet gives no separate electrical limits for it, and the absolute maximum ratings are referenced to GND (VCC to GND -0.3 to 8 V, SW to GND -0.7 to 65 V). |
| 2 | GND | power_in | Ground pin; the datasheet gives no separate electrical limits for it, and the absolute maximum ratings are referenced to GND (VCC to GND -0.3 to 8 V, SW to GND -0.7 to 65 V). |
| 3 | VCC | power_out | Output of the internal LDO that provides bias for the internal circuit and MOSFET driver; a capacitor must be connected to this pin, and VCC to GND is rated -0.3 to 8 V. |
| 4 | NC | unconnected | Not connected internally; the datasheet specifies no function for this pin. |
| 5 | SW | passive | Drain of the internal N-MOS; SW to GND is rated -0.7 to 65 V, and the N-MOS breakdown voltage BVDSS is 60 V. |
| 6 | SW | passive | Drain of the internal N-MOS; SW to GND is rated -0.7 to 65 V, and the N-MOS breakdown voltage BVDSS is 60 V. |
| 7 | SW | passive | Drain of the internal N-MOS; SW to GND is rated -0.7 to 65 V, and the N-MOS breakdown voltage BVDSS is 60 V. |
| 8 | SW | passive | Drain of the internal N-MOS; SW to GND is rated -0.7 to 65 V, and the N-MOS breakdown voltage BVDSS is 60 V. |
