XL7045E1

XLSEMI · DC-DC Converters · ESOP-8

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).
