LM2596HVGR-ADJ from HTC Korea TAEJIN Tech, 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 | Input supply pin; the operating supply range is 4.5 V to 60 V, and the absolute maximum supply voltage is 63 V. |
| 2 | VOUT | power_out | Regulated switching output to the inductor and output capacitor; the output voltage to GND must not go below -1 V and the guaranteed load current is 3.0 A. |
| 3 | GND | power_in | Ground reference pin; the datasheet recommends single-point grounding or a ground plane for best results. |
| 4 | FB/ADJ | input | Output voltage feedback or adjust input, with a nominal 1.23 V feedback voltage on the adjustable version and an absolute maximum range of -0.3 V to 25 V (or VIN). |
| 5 | ON/OFF | input | Shutdown control input with a 0.6 V to 2.0 V threshold (1.3 V typical) and an absolute maximum range of -0.3 V to 60 V (or VIN). |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
