XL2596S-ADJE1 from XLSEMI, in a TO-263-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Supply Voltage Input Pin. Operates from a 4.5V to 40V DC voltage (absolute max 45V). Bypass VIN to GND with a suitably large capacitor (e.g., 470uF/35V) to eliminate noise on the input. |
| 2 | OUTPUT | output | Power Switch Output Pin (SW). This is the internal switch node that supplies power to the output through the external inductor and Schottky diode. Rated for 3A continuous. |
| 3 | GND | power_in | Ground Pin. Care must be taken in layout. This pin should be placed outside of the Schottky Diode to output capacitor ground path to prevent switching ground-current spikes from inducing voltage noise into the XL2596. Metal tab is also GND. |
| 4 | FEEDBACK | input | Feedback Pin (FB). Through an external resistor divider network, FEEDBACK senses the output voltage and regulates it. The feedback threshold voltage is 1.23V (typ). Absolute max -0.3V to VIN. |
| 5 | ON/OFF | input | Enable Pin. Drive ON/OFF pin low to turn on the device; drive it high to turn it off. Floating is default low (enabled). TTL-compatible with hysteresis. Absolute max -0.3V to VIN. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 596 faces against 135 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
