XL33063 from XINLUDA, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Switch Collector | bidirectional | High-current internal switch collector input; the output switch is rated for 1.5 A peak switch current. |
| 2 | Switch Emitter | bidirectional | High-current internal switch emitter output, which is tied to GND through the current-sense path in the step-down application. |
| 3 | Timing Capacitor | passive | Attach a timing capacitor to change the switching frequency (CT = 1.0 nF gives about 33 kHz at 25 C in the electrical characteristics). |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | Comparator Inverting Input | input | Attach to a resistor divider network to create a feedback loop; the comparator threshold is 1.25 V typical. |
| 6 | VCC | power_in | Logic supply voltage, to be tied to VIN; the operating supply range is 3.0 V to 40 V. |
| 7 | IPK Sense | input | Current-limit sense input, with the current-limit sense voltage specified at 250 mV to 350 mV (300 mV typical). |
| 8 | Driver Collector | bidirectional | Darlington pair driving transistor collector input, with the driver collector current rated at 100 mA maximum. |
