OB2226CPA-H

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

OB2226CPA-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 VDD power_in Power supply input. Absolute maximum -0.3V to 40V. Includes internal VDD zener clamp (10 mA continuous), UVLO with hysteresis, and VDD OVP.
2 COMP input Loop compensation pin for constant-voltage (CV) stability. Connect compensation network here. Absolute maximum -0.3V to 7V.
3 NC unconnected Not connected. Leave floating or tie to a safe potential per PCB layout considerations.
4 CS input Current sense input. Senses primary-side switch current through an external sense resistor for cycle-by-cycle current limiting and PWM control. Absolute maximum -0.3V to 7V. Built-in Leading Edge Blanking (LEB).
5 DRAIN output High-voltage MOSFET drain pin (650V BVdss for -H suffix). Connected internally to the integrated power MOSFET drain; ties to the primary lead of the transformer/inductor. Merged with pin 6 for thermal dissipation.
6 DRAIN output High-voltage MOSFET drain pin (650V BVdss for -H suffix). Same net as pin 5; both drain pins are shorted internally and typically connected to a 100 mm^2 copper pad for heat dissipation (RθJA = 90 °C/W).
7 GND power_in Ground pin. Merged with pin 8 as the common IC ground/return. This pin only exists on the SOP8 package (DIP7 has GND on pin 7 only).
8 GND power_in Ground pin. Same net as pin 7; both are the IC signal/power ground reference.

CAD (KiCad official)

  • Symbol: OB2226CPA-H
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: ob2226cpa-h-etched.step / ob2226cpa-h-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ob2226cpa-h.step / ob2226cpa-h.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
ob2226cpa-h.step 122 KB You want the bare part, or you mark your own boards.
ob2226cpa-h-etched.step 2.3 MB You want the part with OB2226CPA-H already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 550 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 (3 pp, sha256 9e905485b95fe125, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
