XH2596-5.0 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 | Positive input supply for the switching regulator (operating range 4.5V to 40V, 45V absolute maximum), needing a low-ESR input bypass capacitor close to the pin. |
| 2 | Output | output | Internal switch output that swings between (+VIN − VSAT) and about −0.5V with duty cycle of about VOUT/VIN, so PC board copper on this pin should be kept to a minimum. |
| 3 | GND | power_in | Circuit ground. |
| 4 | Feedback | input | Senses the regulated output voltage to complete the feedback loop (absolute maximum −0.3V to +25V). |
| 5 | ON/OFF | input | Shutdown logic input: below about 1.3V the regulator is on, above 1.3V (maximum 25V) it shuts down to about 80 µA standby, and it may be tied to ground or left open if unused. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
