D2596HV-ADJ from Silicore, 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, which needs a suitable input bypass capacitor to minimize voltage transients and supply switching currents, with a recommended supply range of 6 V to 60 V (63 V absolute maximum). |
| 2 | OUTPUT | power_out | 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 reference for the regulator. |
| 4 | FEEDBACK | input | Senses the regulated output voltage to complete the feedback loop; on the ADJ version it is the programming divider node, with a feedback bias current of 50 nA typical and 100 nA maximum at VOUT = 5 V, and resistors should not exceed 100 kΩ. |
| 5 | ON / OFF | input | Shuts the regulator down with logic levels: leave grounded or drive below 0.8 V (VIL) for normal operation and drive above 2.0 V (VIH) for standby, within a range of −0.3 V to +VIN, and it should not be left open. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
