XINLUDA · DC-DC Converters · DIP-8

XD33063 from XINLUDA, in a DIP-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, with switch current rated up to 1.5 A and switch collector voltage up to 40 Vdc.
2 Switch Emitter bidirectional High-current internal switch emitter output, with switch emitter voltage rated up to 40 Vdc.
3 Timing Capacitor passive Attach a timing capacitor to change the switching frequency.
4 GND power_in Ground reference pin.
5 Comparator Inverting Input input Attach to a resistor divider network to create a feedback loop; comparator input voltage range is −0.3 V to +40 Vdc.
6 VCC power_in Logic supply voltage that is tied to VIN; power supply voltage is rated 40 Vdc maximum and the datasheet gives an input range of 3.0 V to 40 V.
7 IPK Sense input Current-limit sense input, with a current limit sense voltage of 250 mV min, 300 mV typ, 350 mV max.
8 Driver Collector bidirectional Darlington pair driving transistor collector input, with driver collector voltage rated 40 Vdc and driver collector current rated 100 mA.
