NDP1450KC 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 | FB | input | Feedback input for the output voltage divider; the internal reference is 1.0 V (VREF 0.985 V to 1.015 V), and FB to GND is rated -0.3 V to 6 V. |
| 2 | CSP | input | Positive pole of the current sense; the CSP-to-CSN current-sense voltage is 51 mV to 59 mV, and CSP to GND is rated -0.3 V to 25 V. |
| 3 | CSN1 | input | Negative pole 1 of current sense 1; the CSP-to-CSN1 sense voltage is 51 mV to 59 mV, and CSN1 to GND is rated -0.3 V to 25 V. |
| 4 | CSN2 | input | Negative pole 1 of current sense 2 (labelled 'Current Sense2' in the datasheet); the CSP-to-CSN2 sense voltage is 51 mV to 59 mV, and CSN2 to GND is rated -0.3 V to 25 V. |
| 5 | GND | power_in | Ground reference for the device. |
| 6 | VIN | power_in | Power input; the operating input range is 7 V to 37 V, and VIN to GND is rated -0.3 V to 44 V. |
| 7 | BST | passive | Boot strap pin for the high-side driver; BST to GND is rated -0.3 V to VIN+7 V. |
| 8 | SW | output | Switching node connected to the inductor; SW to GND is rated -0.3 V to VIN+0.3 V. |
