LM2596HVGDP-ADJ from HTC Korea TAEJIN Tech, in a SOP-8-EP. 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 range of 4.5 V to 60 V and an absolute maximum supply voltage of 63 V. |
| 2 | VOUT | power_out | Regulated output to the load, rated for a maximum load current of 3.0 A, with the output voltage to GND limited to a minimum of -1 V. |
| 3 | FB/ADJ | input | Output voltage feedback or adjust input, where VOUT = VFB(1 + R2/R1) with VFB = 1.23 V and FB pin voltage rated -0.3 V to 25 V absolute maximum. |
| 4 | ON/OFF | input | Shutdown control input with a threshold of 0.6 V to 2.0 V (typical 1.3 V), rated -0.3 V to 60 V absolute maximum. |
| 5 | GND | power_in | Ground reference pin, which is one of four GND pins (5 to 8) on the SOP-8PP package. |
| 6 | GND | power_in | Ground reference pin, which is one of four GND pins (5 to 8) on the SOP-8PP package. |
| 7 | GND | power_in | Ground reference pin, which is one of four GND pins (5 to 8) on the SOP-8PP package. |
| 8 | GND | power_in | Ground reference pin, which is one of four GND pins (5 to 8) on the SOP-8PP package. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
