SCT2450STER from SCT, in a ESOP-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 | BOOT | power_in | Power supply bias for high-side power MOSFET gate driver. Connect a 0.1uF bootstrap capacitor from BOOT pin to SW pin. Bootstrap capacitor is charged when low-side power MOSFET is on or SW voltage is low. Absolute max 44V; BOOT-SW max 6V. |
| 2 | VIN | power_in | Input supply voltage, 3.8V to 36V operating range. Connect a local bypass capacitor from VIN pin to GND pin. Path from VIN pin to high frequency bypass capacitor and GND must be as short as possible. |
| 3 | EN | input | Enable pin to the regulator with internal pull-up current source (1.5uA typ at 1V). Pull below 1.1V to disable the converter. Float or connect to VIN to enable the converter. A resistor divider from VIN to GND connecting EN can adjust the input voltage lockout threshold. Enable high threshold 1.18V typ. |
| 4 | RT/CLK | bidirectional | Sets internal oscillator clock frequency (100kHz to 1.1MHz) via a resistor from this pin to ground, or synchronizes to an external clock input applied directly to the pin. Internal oscillator synchronizes to the external clock frequency with PLL. If detected clocking edges stop, operation automatically returns to resistor-programmed frequency. Absolute max 6V. |
| 5 | FB | input | Inverting input of the trans-conductance error amplifier. Tap of external feedback resistor divider from output to GND sets output voltage. Device regulates FB to internal reference of 0.8V typical (±1%). Absolute max 6V. |
| 6 | COMP | output | Error amplifier output. Connect to frequency loop compensation network. Error amp transconductance 300uS typ; COMP high clamp 3V, low clamp 0.4V. Absolute max 6V. |
| 7 | GND | power_in | Ground return for the device. Connect to system ground plane; also tie to Thermal Pad (pin 9) for proper operation. |
| 8 | SW | power_out | Regulator switching output. Connect SW to an external power inductor. Supports up to 5A continuous output current. Absolute max range -1V to 38V. |
| 9 | Thermal Pad | passive | Heat dissipation path of die. Electrically connect to GND pin. Must be connected to ground plane on PCB for proper operation and optimized thermal performance. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 587 faces against 152 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.
