NDP7931AKC

NDP · AC-DC Controllers And Regulators · SOP-8

NDP7931AKC 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 GND power_in Ground pin; the datasheet gives no separate electrical limits for it, and the absolute maximum ratings are referenced to GND (VCC to GND -0.3 to 8 V, SW to GND -0.7 to 65 V).
2 GND power_in Ground pin; the datasheet gives no separate electrical limits for it, and the absolute maximum ratings are referenced to GND (VCC to GND -0.3 to 8 V, SW to GND -0.7 to 65 V).
3 VCC power_out Output of the internal LDO that provides bias for the internal circuit and MOSFET driver; a capacitor must be connected to this pin, and VCC to GND is rated -0.3 to 8 V.
4 NC unconnected Not connected internally; the datasheet specifies no function for this pin.
5 SW passive Drain of the internal N-MOS; SW to GND is rated -0.7 to 65 V, and the N-MOS breakdown voltage BVDSS is 60 V.
6 SW passive Drain of the internal N-MOS; SW to GND is rated -0.7 to 65 V, and the N-MOS breakdown voltage BVDSS is 60 V.
7 SW passive Drain of the internal N-MOS; SW to GND is rated -0.7 to 65 V, and the N-MOS breakdown voltage BVDSS is 60 V.
8 SW passive Drain of the internal N-MOS; SW to GND is rated -0.7 to 65 V, and the N-MOS breakdown voltage BVDSS is 60 V.

CAD (KiCad official)

  • Symbol: NDP7931AKC
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: ndp7931akc-etched.step / ndp7931akc-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ndp7931akc.step / ndp7931akc.glb are the bare package body.
