D2596HV-5.0 from Silicore(芯谷), in a TO263-5. 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, which needs a suitable input bypass capacitor to minimize voltage transients; recommended supply voltage is 6 to 60 V with an absolute maximum of 63 V. |
| 2 | OUTPUT | output | Internal switch output that swings between (+VIN - VSAT) and approximately -0.5 V, so the PC board copper connected to it should be kept to a minimum to limit coupling to sensitive circuitry. |
| 3 | GND | power_in | Circuit ground for the regulator. |
| 4 | FEEDBACK | input | Senses the regulated output voltage to complete the feedback loop. |
| 5 | ON / OFF | input | Allows the switching regulator to be shut down with logic-level signals, with the pin voltage limited to -0.3 V up to +VIN. |
