OB5269BCPA

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

OB5269BCPA 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 BO input Brownout protection input. Connect a resistor divider from bulk/line to this pin. Vth_bo ≈ 0.82 V (release Vth_bo_H ≈ 0.95 V), Td_brownout ≈ 60-80 ms. Absolute max -0.3 to 7 V.
2 FB input Feedback input pin. PWM duty cycle is determined by the voltage on this pin combined with the CS current-sense signal. V_FB open ≈ 3.9-5 V, input impedance ≈ 25 kΩ, absolute max -0.3 to 7 V.
3 CS input Current sense input from MOSFET source resistor. Internal cycle-by-cycle OCP threshold Vth_OC ≈ 0.75 V, leading-edge blanking ≈ 320 ns, input impedance ≈ 40 kΩ. Absolute max -0.3 to 7 V.
4 GND power_in Ground reference for the IC. Return for VDD and all internal circuitry.
5 GATE output Totem-pole gate driver output for the external power MOSFET. VOH ≥ 8 V, VOL ≤ 1 V @ Io=20 mA, output clamped to ~15 V. Rise ≈ 70 ns / fall ≈ 30 ns into 1 nF.
6 VDD power_in Chip power supply. Recommended 12-23.5 V; UVLO(on) ≈ 9.3 V, UVLO(off/recovery) ≈ 15.3 V, OVP ≈ 26 V (latched). Zener clamp ≈ 32 V, absolute max 30 V DC.
7 NC unconnected No connection. Leave floating.
8 HV power_in High-voltage startup pin. Connect via resistor(s) to the line input or bulk capacitor. Supplies startup current (IHV ≈ 1-5 mA at VDD=2 V) and switches off after startup (leakage ≤ 10 µA at HV=500 V). Absolute max -0.3 to 500 V.

Ordering variants

Same part, different packaging or reel option.

  • OB5269BCPA

CAD (KiCad official)

  • Symbol: OB5269BCPA
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: ob5269bcpa-etched.step / ob5269bcpa-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ob5269bcpa.step / ob5269bcpa.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
ob5269bcpa.step 122 KB You want the bare part, or you mark your own boards.
ob5269bcpa-etched.step 2.4 MB You want the part with OB5269BCPA already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 578 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 26f6481e4e2e86ef, 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).
