XL7045E1 from XLSEMI, in a ESOP-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 | VIN | power_in | Power input pin; an electrolytic capacitor must be connected in parallel between VIN and GND to suppress noise, with input voltage specified at 10 V to 80 V and an absolute maximum of -0.3 V to 100 V. |
| 2 | SW | output | Power switch output pin and the switching node of the converter, with an absolute maximum voltage of -0.3 V to Vin. |
| 3 | FB | input | Feedback pin that senses the output voltage through an external resistor divider, with a reference voltage of 1.25 V and an absolute maximum voltage of -0.3 V to Vin. |
| 4 | GND | power_in | Ground pin, which is also the potential of the exposed back pad. |
| 5 | CSP | input | Positive current-sense input, with an absolute maximum voltage of -0.3 V to 20 V. |
| 6 | CSN | input | Negative current-sense input, with an absolute maximum voltage of -0.3 V to 20 V. |
| 7 | NC | unconnected | No connection. |
| 8 | NC | unconnected | No connection. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
