OB2225RCPA-H from OB On Bright Elec, in a SOIC-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 and output voltage feedback pin. Recommended operating range 8 to 12V; absolute maximum -0.3 to 20V. UVLO with hysteresis and OVP are monitored on this pin. |
| 2 | GND | power_in | Device ground reference for the controller and MOSFET source return. |
| 3 | NC | unconnected | No connect. Should be left floating or tied to GND during normal operation. |
| 4 | CS | input | Current sense input for cycle-by-cycle peak current limiting and current-mode PWM control. Absolute maximum -0.3 to 7V. |
| 5 | Drain | output | Internal high-voltage power MOSFET drain (BVdss = 650V per H-suffix). Pins 5/6/7/8 are tied together internally to improve current handling and thermal dissipation; connect all four to the switching node. |
| 6 | Drain | output | Internal high-voltage power MOSFET drain (tied to pins 5/7/8). |
| 7 | Drain | output | Internal high-voltage power MOSFET drain (tied to pins 5/6/8). |
| 8 | Drain | output | Internal high-voltage power MOSFET drain (tied to pins 5/6/7). |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 593 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.
