NDP2345KC

NDP · DC-DC Converters · SOP-8

NDP2345KC 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 Output voltage feedback input compared against the internal 1.0V reference (VFB 0.980V to 1.02V), with FB-to-GND absolute maximum of -0.3V to +6V.
2 NC unconnected No connection; the datasheet gives no electrical function for this pin.
3 EN input Enable input where a rising threshold of 1.5V enables switching and a falling threshold of 0.6V disables it, with EN-to-GND absolute maximum of -0.3V to 25V.
4 VIN power_in Power input with an operating range of 5.5V to 30V, and VIN-to-GND absolute maximum of -0.3V to 34V.
5 SW output Switching node connected to the inductor, with SW-to-GND absolute maximum of -0.3V to VIN+0.3V.
6 SW output Switching node connected to the inductor, with SW-to-GND absolute maximum of -0.3V to VIN+0.3V.
7 GND power_in Ground reference for the device.
8 GND power_in Ground reference for the device.

CAD (KiCad official)

  • Symbol: NDP2345KC
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: ndp2345kc-etched.step / ndp2345kc-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ndp2345kc.step / ndp2345kc.glb are the bare package body.
