XBL4001DTR from XBLW, in a SOP-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 | SW | power_out | Power switch output pin; SW is the switch node that supplies power to the output. |
| 2 | SW | power_out | Power switch output pin; SW is the switch node that supplies power to the output. |
| 3 | GND | power_in | Ground pin; place it outside of the Schottky diode to output capacitor ground path to prevent switching current spikes from inducing voltage noise into the XBL4001. |
| 4 | FB | input | Feedback pin; an external resistor divider senses and regulates the output voltage, with a feedback threshold of 1.235V. |
| 5 | CS | input | Output current sense pin, with ILOAD=0.155V/Rcs. |
| 6 | EN | input | Enable pin; drive high or float to turn on the device, drive low to turn it off. |
| 7 | VIN | power_in | Supply voltage input pin, operating from 4.5V to 40V DC; bypass VIN to GND with a suitably large capacitor to eliminate noise on the input. |
| 8 | VIN | power_in | Supply voltage input pin, operating from 4.5V to 40V DC; bypass VIN to GND with a suitably large capacitor to eliminate noise on the input. |
