NDP1340KC 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, with the internal reference at 1.0 V (0.985 to 1.015 V) and an FB bias current of 0.2 µA. |
| 2 | CSP | input | Positive pole of the current sense input; the CSP-CSN sense voltage is 57 to 63 mV (60 mV typ), and CSP to GND is rated -0.3 to 25 V. |
| 3 | CSN | input | Negative pole of the current sense input; used with CSP for the current sense amplifier, and CSN to GND is rated -0.3 to 25 V. |
| 4 | VIN | power_in | Power input for the converter, rated for an input voltage range of 7 V to 30 V, with VIN to GND absolute maximum of -0.3 to 33 V and overvoltage protection at 32 V. |
| 5 | SW | output | Switching node connected to the inductor; SW to GND is rated -0.3 V to VIN+0.3 V. Pin 5 and pin 6 are both listed as SW in the datasheet. |
| 6 | SW | output | Switching node connected to the inductor; SW to GND is rated -0.3 V to VIN+0.3 V. Pin 5 and pin 6 are both listed as SW in the datasheet. |
| 7 | FS | input | Frequency setting pin: a resistor to GND sets the switching frequency (130 kHz floating up to 300 kHz with 470 kΩ), and FS below 0.3 V shuts the device down; FS to GND is rated -0.3 to 6 V. |
| 8 | GND | power_in | Ground reference pin for the device. |
