OB2235NCPA-H

OB On Bright Elec · AC-DC Controllers and Regulators · SOP-8

OB2235NCPA-H from OB On Bright Elec, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND power_in Ground reference for the controller and internal power MOSFET source. Tied together with pin 2 internally.
2 GND power_in Ground reference for the controller and internal power MOSFET source. Tied together with pin 1 internally.
3 NC unconnected No connect. Should be left floating or connected to GND during normal operation.
4 VDD power_in Controller power supply and output voltage feedback pin. Internally regulated to ~12.1V average; UVLO_ON ≈7.0V (falling), UVLO_OFF ≈13.5V (rising), OVP ≈17.5V. Operating range 8 to 12V; absolute max 18V.
5 Drain power_in Drain of the internal 650V power MOSFET. Pins 5/6/7/8 are tied together to share current and improve thermal dissipation. Rdson ≈9Ω (OB2235N).
6 Drain power_in Drain of the internal 650V power MOSFET (tied to pins 5/7/8).
7 Drain power_in Drain of the internal 650V power MOSFET (tied to pins 5/6/8).
8 Drain power_in Drain of the internal 650V power MOSFET (tied to pins 5/6/7).

CAD (KiCad official)

  • Symbol: OB2235NCPA-H
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: ob2235ncpa-h-etched.step / ob2235ncpa-h-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ob2235ncpa-h.step / ob2235ncpa-h.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
ob2235ncpa-h.step 122 KB You want the bare part, or you mark your own boards.
ob2235ncpa-h-etched.step 2.4 MB You want the part with OB2235NCPA-H already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 582 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: OB On Bright Elec datasheet (12 pp, sha256 d3bc0bc6f818db01, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
