OB2506PCPA

OB On Bright Elec · Battery Management · SOP-8

OB2506PCPA 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 FB input Feedback input pin. PWM duty cycle is determined by the voltage level on this pin combined with the current-sense signal at CS. Open-loop voltage ~5V, internally pulled up via ~15kΩ / 35µA. Burst mode enter/exit thresholds ~0.95V/1.05V.
2 VCC power_in Chip power supply. Recommended operating range 8V to 25V, absolute max 28V. UVLO(ON) ~7.0V, UVLO(OFF) ~18.2V; VCC OVP ~27V. Typically supplied from transformer auxiliary winding after startup.
3 AUX input Voltage feedback from the auxiliary winding via a resistor divider, reflecting the output voltage. Sampled mid-demagnetization; used for output OVP (V_OVP ~3.0V) and AC line-voltage compensation of the CC threshold.
4 CS input Current-sense input. Primary MOSFET source current is sensed through an external resistor Rs to program the CC point and maximum output power. Vth_ocp ~500mV typ (min 485mV, max 515mV); LEB ~300ns integrated so no external RC filter is required.
5 Drain output Drain of the internal high-voltage power MOSFET (600V BVdss). Tied together with pin 6 to increase current handling; connects to the primary winding of the flyback transformer. Rds(on) ~4Ω for OB2506P.
6 Drain output Second drain pin of the internal power MOSFET, connected in parallel with pin 5 for improved current/thermal capability.
7 GND power_in Device ground. Pins 7 and 8 are both labeled GND and should be tied together to the primary-side ground return.
8 GND power_in Device ground (second GND pin). Tie to pin 7 for the primary-side return path.

CAD (KiCad official)

  • Symbol: OB2506PCPA
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: ob2506pcpa-etched.step / ob2506pcpa-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ob2506pcpa.step / ob2506pcpa.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
ob2506pcpa.step 122 KB You want the bare part, or you mark your own boards.
ob2506pcpa-etched.step 2.3 MB You want the part with OB2506PCPA already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 560 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 (10 pp, sha256 d0f66623d2b810db, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
