UCC5350SBDR from Texas Instruments, 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 | VCC1 | power_in | Input-side (primary) supply voltage, 3 V to 15 V. Connect a locally decoupled low-ESR/ESL capacitor to GND1 as close to the device as possible. |
| 2 | IN+ | input | Noninverting gate-drive voltage-control input with CMOS input threshold. Internally pulled low if left open. Referenced to GND1. |
| 3 | IN- | input | Inverting gate-drive voltage-control input with CMOS input threshold. Internally pulled high if left open. Referenced to GND1. |
| 4 | GND1 | power_in | Primary-side input ground. All input-side signals (VCC1, IN+, IN-) are referenced to this ground. |
| 5 | VCC2 | power_in | Secondary-side positive output supply rail (up to 33 V). Use a low-ESR/ESL decoupling capacitor to VEE2 located as close to the device as possible. |
| 6 | OUTH | output | Gate-drive pull-up (source) output found on the UCC53x0S split-output version. Sources ≥5 A into the external power switch gate; typically tied to the gate through a series turn-on resistor. |
| 7 | OUTL | output | Gate-drive pull-down (sink) output found on the UCC53x0S split-output version. Sinks ≥5 A from the external power switch gate; typically tied to the gate through a series turn-off resistor to allow independent tuning of on/off speed. |
| 8 | VEE2 | power_in | Secondary-side negative output supply rail (or GND for S/M versions). Connect a locally decoupled low-ESR/ESL capacitor to VCC2 as close to the device as possible. Serves as the reference for the isolated output stage. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 662 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.
