NCP3065DR2G from onsemi, 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 | Switch Collector | output | Internal Darlington switch collector. Rated 0 to +40 V (VSWC); connects to the switching node in buck/boost topologies. Switch current rating 1.5 A. |
| 2 | Switch Emitter | output | Internal Darlington switch emitter. Rated -0.6 V to +VCC (VSWE); typically returns to ground or forms the switching node depending on topology. Switch current rating 1.5 A. |
| 3 | CT | passive | Timing Capacitor / Oscillator Input. External capacitor sets the oscillator frequency (e.g. 2.2 nF -> ~150 kHz typ). Rated -0.2 to +1.4 V. |
| 4 | GND | power_in | Ground pin for all internal circuits. Reference for all voltage measurements on the device. |
| 5 | Comparator Inverting Input | input | Inverting input pin of the internal comparator; compared against the 235 mV (typ) reference for LED current feedback. Input range -0.2 V to +VCC. |
| 6 | VCC | power_in | Voltage supply. Operating range 3.0 V to 40 V; typical supply current 7 mA max. |
| 7 | Ipk Sense | input | Peak Current Sense Input. Monitors the voltage drop across an external sense resistor to limit the peak switch current (VIPK(Sense) typ 185 mV). Input range -0.2 V to VCC+0.2 V. |
| 8 | NC | unconnected | No connect. Pin not connected internally; may be left floating or tied to ground. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 620 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.
