LM2594HVMX-ADJ from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No internal connection; must be soldered to PCB for thermal management. |
| 2 | NC | unconnected | No internal connection; must be soldered to PCB for thermal management. |
| 3 | NC | unconnected | No internal connection; must be soldered to PCB for thermal management. |
| 4 | Feedback | input | Feedback input senses regulated output voltage to complete feedback loop. |
| 5 | ON/OFF | input | Shutdown control input; pulling below 1.3 V enables regulator (ON) and pulling above 1.3 V up to 25 V maximum disables it (OFF). |
| 6 | Ground | power_in | Circuit ground. |
| 7 | +VIN | power_in | Positive input supply requiring bypass capacitor to minimize voltage transients and supply switching currents. |
| 8 | Output | output | Output switch with voltage swing between (+VIN − VSAT) and −0.5 V at duty cycle VOUT/VIN; minimize PCB copper area to reduce coupling to sensitive circuitry. |
