LM2592HVS-12 from HGSEMI, 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 limit voltage transients; the datasheet gives an operating supply range of 4.5V to 60V and an absolute maximum supply voltage of 63V. |
| 2 | Output | output | Internal switch output that swings between (VIN - VSAT) and about -0.5V at a duty cycle of approximately VOUT/VIN, so its PC board copper area should be kept to a minimum to reduce coupling. |
| 3 | GND | power_in | Circuit ground for the regulator, to which the input and output capacitors and the ON/OFF pin return when shutdown is not used. |
| 4 | Feedback | input | Senses the regulated output voltage to close the feedback loop; the feedback pin voltage is limited to -0.3V to +25V, and on the adjustable version the R1/R2 divider sets VOUT with VREF = 1.23V. |
| 5 | ON/OFF | input | Logic input for shutdown: pulling it below about 1.3V turns the regulator on and pulling it above 1.3V (maximum 25V) shuts it down, while leaving it open or tying it to ground keeps the regulator on. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
