HTC Korea TAEJIN Tech · DC-DC Converters · TO-263-5
LM2596HVGR-12 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, with an operating supply range of 4.5V to 60V and an absolute maximum supply voltage of 63V. |
| 2 | VOUT | power_out | Regulator output pin that delivers the switched and filtered output voltage to the load, rated for up to 3.0A load current. |
| 3 | GND | power_in | Ground pin; the datasheet recommends single-point grounding or a ground-plane construction for best results. |
| 4 | FB/ADJ | input | Output voltage feedback or adjust input, with a feedback voltage of 1.23V (typical) on the adjustable version and an absolute maximum of 25V (or VIN). |
| 5 | ON/OFF | input | External shutdown input with a typical threshold of 1.3V (limits 0.6V to 2.0V) and an absolute maximum of 60V (or VIN), where the device draws about 30µA standby current when shut down. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
