XH2576-12

XINLUDA · DC-DC Converters · TO-263-5

XH2576-12 from XINLUDA, in a TO-263-5. 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 pin connected to the collector of the high-side transistor; connect to the power supply and input bypass capacitor CIN, keeping the path from VIN to CIN and GND as short as possible.
2 OUTPUT output Emitter of the power transistor and switching node; connect to the inductor and the cathode of the external catch diode.
3 GROUND power_in Ground pin; the path to CIN must be as short as possible, and on the TO-263 package this pin and the tab are both ground and either may be used.
4 FEEDBACK input Feedback sense input; connect to the midpoint of the feedback divider to set VOUT on the ADJ version, or directly to the output capacitor on fixed-output versions.
5 ON/OFF input Enable input where high = OFF and low = ON (device is in shutdown above 1.4 V and switching below 1.2 V); connect to GND to enable and do not leave it floating.
6 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
