D2596HV-12 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; the recommended supply range is 6 V 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 this pin 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 close the feedback loop, and for the fixed-voltage version it must be wired to the output voltage point of the supply. |
| 5 | ON / OFF | input | Shuts the regulator down with logic-level signals: the pin must be low (VIL max 0.8 V) for normal operation or high (VIH min 2.0 V) for standby, must not be left open, and its input voltage is limited to -0.3 V to +VIN. |
