OB2222MCPA

OB On Bright Elec · AC-DC Controllers and Regulators · SOP-8-150mil

OB2222MCPA from OB On Bright Elec, in a SOP-8-150mil. 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 FB input Output voltage feedback input. This pin should connect a capacitor to ground. Regulated internally so the FB voltage is driven to an average of ~5.15V; open-loop protection trips at Vth_OLD ~0.515V.
2 GND power_in Ground reference for the controller and internal power BJT emitter return.
3 VDD power_in Chip power supply. Recommended 4.5-6V; absolute max 20V. UVLO(ON) ~3.7V rising is actually UVLO exit at 11.5V typ; UVLO(OFF) enter ~3.7V falling. OVP threshold 15V typ. Startup current 10uA max.
4 CS input Current sense input. Senses inductor/BJT current via an external sense resistor. Over-current threshold Vth_oc ~575mV, short-circuit threshold Vth_scp ~0.7V, CS-floating protection ~1.0V. Internal Leading Edge Blanking (~300ns) removes need for external RC filter. Absolute max -0.3 to 7V.
5 C output Power bipolar collector pin. Internally tied to pins 6, 7, 8 (all four are the high-voltage BJT collector, C-B breakdown 700V, C-E breakdown 450V, Ic peak 1.0A). Multiple pins improve current handling and thermal dissipation.
6 C output Power bipolar collector pin (parallel with pins 5, 7, 8).
7 C output Power bipolar collector pin (parallel with pins 5, 6, 8).
8 C output Power bipolar collector pin (parallel with pins 5, 6, 7).

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
ob2222mcpa.step 122 KB You want the bare part, or you mark your own boards.
ob2222mcpa-etched.step 2.2 MB You want the part with OB2222MCPA already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 532 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 (9 pp, sha256 99b88677c19fa7bb, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
