SCT2632ASTER 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 the high-side power MOSFET gate driver. Connect a 0.1µF bootstrap capacitor from BOOT to SW; the cap charges when SW is low. Absolute max 71V (BOOT-SW max 6V). |
| 2 | VIN | power_in | Input supply voltage, 4.5V to 60V operating range. Connect a local bypass capacitor from VIN to GND; the path from VIN to the high-frequency bypass cap and GND must be as short as possible. |
| 3 | EN | input | Enable pin with internal pull-up (1µA/4µA). Pull below 1.05V to disable; float or tie to VIN to enable. A resistor divider from VIN to GND on EN programs the input UVLO threshold (VEN_H = 1.2V typ). |
| 4 | RT/CLK | bidirectional | Sets the internal oscillator switching frequency (100kHz-1.2MHz) via a resistor to GND, or accepts an external clock for PLL synchronization. If the external clock stops, the part automatically reverts to the resistor-programmed frequency. Typical pin voltage 0.5V; do not float or short to GND. |
| 5 | FB | input | Inverting input of the trans-conductance error amplifier. External resistor divider from VOUT to GND to FB sets the output voltage; the device regulates FB to the internal 0.8V ±1% reference. |
| 6 | SS | passive | Soft-start programming pin. Connect a capacitor from SS to GND; an internal 3µA source charges CSS to program soft-start time (tSS = CSS × 0.8V / 3µA). Programmed soft-start time should be greater than 4ms. |
| 7 | GND | power_in | Device ground return. Bond to the ground plane together with the thermal pad. |
| 8 | SW | power_out | Regulator switching output - drain of the internal high-side MOSFET. Connect to the external power inductor. Absolute max range -1V to 65V. |
| 9 | Thermal Pad | passive | Exposed die-attach pad for heat dissipation. Electrically connected to GND (pin 7) and must be soldered to the PCB ground plane for correct operation and optimized thermal performance (θJA = 42°C/W on the standard board). |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 639 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.
