Silicore(芯谷) · DC-DC Converters · TO-263-5L
D2596-5.0 from Silicore(芯谷), in a TO-263-5L. 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 the switching currents; the recommended supply range is 6 V to 40 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 close the feedback loop, and for fixed-voltage versions it must be wired to the output voltage point. |
| 5 | ON / OFF | input | Logic-level shutdown input where the pin is grounded or driven below about 1.6 V for normal operation and driven high to enter standby, and it must not be left open. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
