NDP2355KC

NDP · DC-DC Converters · SOP-8

NDP2355KC 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 the output voltage; the internal reference is 1.0V (VFB 0.980V to 1.02V) and VFB bias current is 0.2µA.
2 NC unconnected Not connected; the datasheet assigns no function to this pin.
3 EN input Enable input: switching is enabled when EN rises above 1.5V and disabled when EN falls below 0.6V, with an absolute maximum of 25V to GND.
4 VIN power_in Positive power input; the operating input voltage range is 5.5V to 30V, with an absolute maximum of 33V to GND.
5 SW output Switching node connected to the inductor; SW to GND is rated -0.3V to VIN+0.3V.
6 SW output Switching node connected to the inductor (second SW pin); SW to GND is rated -0.3V to VIN+0.3V.
7 GND power_in Ground reference for the device.
8 GND power_in Ground reference for the device.
