LM2596HVGR-5.0 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 voltage range is 4.5 V to 60 V, with an absolute maximum supply voltage of 63 V. |
| 2 | VOUT | power_out | Regulated output voltage pin that drives the load through the internal switch; the output-to-GND absolute minimum is -1 V. |
| 3 | GND | power_in | Ground reference pin for the regulator. |
| 4 | FB/ADJ | input | Output voltage feedback input on the fixed-output versions and output adjust input on the adjustable version, referenced to VFB = 1.23 V; the feedback pin voltage absolute maximum is 25 V (or VIN). |
| 5 | ON/OFF | input | Shutdown control input with a threshold of 0.6 V to 2.0 V (1.3 V typical) and an absolute maximum input voltage of 60 V (or VIN); the device enters standby with about 30 µA typical supply current. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
