XL2576HVS-ADJE1

XLSEMI · DC-DC Converters · TO-263-5L

XL2576HVS-ADJE1 from XLSEMI, in a TO-263-5L. 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 Supply input for the 4.5V to 50V operating range, requiring an electrolytic capacitor in parallel between VIN and GND to suppress noise.
2 SW output Power switch output pin, serving as the switch node of the output power stage.
3 GND power_in Ground pin for the device.
4 FB input Feedback pin that senses the output voltage through an external resistor divider, with a 1.23V reference voltage for the adjustable version.
5 EN input Enable pin, active low: low level enables operation, high level shuts the device down, and it defaults to low when left floating.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
