OB2225NCPA

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

OB2225NCPA from OB On Bright Elec, in a SOIC-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 VDD power_in Power supply pin and output voltage feedback. Recommended supply range 8V to 12V; absolute max 20V. Also used for output voltage sensing to regulate the 12V output.
2 GND power_in Ground reference for the IC.
3 NC unconnected No connection. Should be left floating or tied to ground during normal operation.
4 CS input Current sense input for cycle-by-cycle peak current limiting of the internal power MOSFET. Absolute maximum input voltage -0.3V to 7V.
5 Drain output Drain of the internal high-voltage power MOSFET. Pins 5/6/7/8 are internally connected and provide the switching node; multiple pins for current handling and thermal dissipation (100mm² PCB copper clad recommended).
6 Drain output Drain of the internal high-voltage power MOSFET. Pins 5/6/7/8 are internally connected; used for current handling and thermal dissipation.
7 Drain output Drain of the internal high-voltage power MOSFET. Pins 5/6/7/8 are internally connected; used for current handling and thermal dissipation.
8 Drain output Drain of the internal high-voltage power MOSFET. Pins 5/6/7/8 are internally connected; used for current handling and thermal dissipation.

  • Symbol: OB2225NCPA
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: ob2225ncpa-etched.step / ob2225ncpa-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ob2225ncpa.step / ob2225ncpa.glb are the bare package body.

Provenance

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

  • Datasheet: OB On Bright Elec datasheet (None pp, sha256 31fd355b6eb15573, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
