LM2592HVSX-ADJ from Texas Instruments, 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 IC switching regulator; requires suitable input bypass capacitor to minimize voltage transients and supply switching currents; recommended operating range 4.5 V to 60 V. |
| 2 | Output | output | Internal switch output pin; voltage switches between approximately (+VIN − VSAT) and approximately −0.5 V with duty cycle of VOUT/VIN. |
| 3 | Ground | power_in | Circuit ground. |
| 4 | Feedback | input | Senses the regulated output voltage to complete the feedback loop; for Adjustable version, set to 1.23 V by means of resistive divider from output; small-signal Schottky diode to Ground recommended for VIN > 40 V when feedforward capacitor is present. |
| 5 | ON/OFF | input | Shutdown control; regulator in shutdown mode drawing about 90 μA when driven high (≥ 2 V), normal operation when floating or driven low (≤ 0.6 V); typical threshold 1.3 V; maximum pin voltage 25 V. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
