NDP2435KC 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 | Feedback input for output voltage regulation, compared against the internal 1.0 V reference, with absolute maximum rating FB to GND of -0.3 V to +6 V. |
| 2 | NC | unconnected | No connection; the datasheet gives no function for this pin. |
| 3 | EN | input | Enable input; the electrical characteristics list an EN shut-down level VEN of 0.7 V. |
| 4 | VIN | power_in | Power input positive pole, operating over 5.5 V to 40 V with an absolute maximum VIN to GND rating of -0.3 V to 45 V. |
| 5 | SW | output | Switching node connected to the inductor, rated SW to GND from -0.3 V to VIN+0.3 V. |
| 6 | SW | output | Switching node connected to the inductor (pin 6 is listed together with pin 5 as SW), rated SW to GND from -0.3 V to VIN+0.3 V. |
| 7 | GND | power_in | Ground reference for the device. |
| 8 | GND | power_in | Ground reference for the device (pin 8 is listed together with pin 7 as GND). |
