NDP2345KC 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 | VFB | input | Output voltage feedback input compared against the internal 1.0V reference (VFB 0.980V to 1.02V), with FB-to-GND absolute maximum of -0.3V to +6V. |
| 2 | NC | unconnected | No connection; the datasheet gives no electrical function for this pin. |
| 3 | EN | input | Enable input where a rising threshold of 1.5V enables switching and a falling threshold of 0.6V disables it, with EN-to-GND absolute maximum of -0.3V to 25V. |
| 4 | VIN | power_in | Power input with an operating range of 5.5V to 30V, and VIN-to-GND absolute maximum of -0.3V to 34V. |
| 5 | SW | output | Switching node connected to the inductor, with SW-to-GND absolute maximum of -0.3V to VIN+0.3V. |
| 6 | SW | output | Switching node connected to the inductor, with SW-to-GND absolute maximum of -0.3V to VIN+0.3V. |
| 7 | GND | power_in | Ground reference for the device. |
| 8 | GND | power_in | Ground reference for the device. |
