XL2843 from XINLUDA, in a SOP-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 COMP output Error Amplifier output; made available for external loop compensation (typically an R-C network to VFB).
2 VFB input Inverting input of the internal Error Amplifier. Normally connected to the switching supply output via a resistor divider; internal reference at this node is 2.50 V.
3 ISENSE input Current-sense input. A voltage proportional to inductor/switch current is applied here; the PWM comparator terminates the output pulse when this pin reaches ~1 V, providing cycle-by-cycle current limiting.
4 RT/CT passive Oscillator timing pin. Connect RT from VREF to this pin and CT from this pin to GND to program the oscillator frequency and maximum duty cycle. Operation up to 500 kHz.
5 GROUND power_in Combined control-circuitry and power ground. Reference for all voltages; timing and bypass caps must be returned here in a single-point ground.
6 OUTPUT output Totem-pole gate-drive output for an external N-channel power MOSFET. Sources and sinks peak currents up to ±1 A; low in the OFF state. VOH typ 13.5 V @ 200 mA source, VOL typ 1.6 V @ 200 mA sink.
7 VCC power_in Positive supply for the control IC. Recommended operating supply 12-28 V; UVLO turn-on 8.4 V typ, turn-off 7.6 V typ (XL2843). Absolute max low-impedance supply 30 V; internal zener clamps at ~34 V.
8 VREF power_out Buffered 5.0 V trimmed reference output (5.00 V typ, ±1% at 25 °C). Supplies charging current for CT through RT; source current limited to 20 mA (recommended), internally short-circuit protected.
