NDP2435KC

NDP · DC-DC Converters · SOP-8

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).
