OB2502PCPA

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

OB2502PCPA 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 for the controller. Recommended operating range 8 to 25V; UVLO(OFF) exit ~18.2V, UVLO(ON) enter ~7.0V, VDD OVP ~27V, absolute max 28.5V.
2 GND power_in Ground return for the controller and internal power MOSFET source-side reference.
3 FB input Voltage feedback from the auxiliary winding. Connect to a resistor divider from the auxiliary winding that reflects the output voltage. Internal reference Vref_FB = 2.5V; also feeds Output OVP (V_OVP ~3.0V).
4 CS input Current sense input from the power MOSFET source via external sense resistor Rs. Used for cycle-by-cycle OCP (Vth_ocp ~500mV) and CC-mode current regulation (Vcs_min ~135mV).
5 Drain power_out Drain of the integrated 650V/2A power MOSFET. Pins 5,6,7,8 are internally tied to the MOSFET drain and should be connected together to the transformer primary switching node. Rdson typ 4Ω.
6 Drain power_out Drain of the integrated 650V/2A power MOSFET (tied to pins 5,7,8).
7 Drain power_out Drain of the integrated 650V/2A power MOSFET (tied to pins 5,6,8).
8 Drain power_out Drain of the integrated 650V/2A power MOSFET (tied to pins 5,6,7). Multiple pins improve thermal and current handling.

Same part, different packaging or reel option.

  • OB2502PCPA

CAD (KiCad official)

  • Symbol: OB2502PCPA
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: ob2502pcpa-etched.step / ob2502pcpa-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ob2502pcpa.step / ob2502pcpa.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
ob2502pcpa.step 122 KB You want the bare part, or you mark your own boards.
ob2502pcpa-etched.step 2.3 MB You want the part with OB2502PCPA already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 551 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 (11 pp, sha256 4ab9cb3c1699c31b, 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).
