LM2594MX-12 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 best heat transfer. |
| 2 | NC | unconnected | No internal connection; must be soldered to PCB for best heat transfer. |
| 3 | NC | unconnected | No internal connection; must be soldered to PCB for best heat transfer. |
| 4 | Feedback | input | Feedback input senses the regulated output voltage to complete the feedback loop; input voltage range −0.3 V to 25 V. |
| 5 | ON/OFF | input | ON/OFF logic input for shutdown control with threshold voltage approximately 1.3 V (regulator ON below, OFF above); maximum input voltage 25 V. |
| 6 | Ground | power_in | Circuit ground reference. |
| 7 | +VIN | power_in | Positive input supply for the IC switching regulator with voltage range 4.5 V to 40 V; suitable low-ESR bypass capacitor required. |
| 8 | Output | output | Internal switch output with voltage range (VIN − VSAT) to approximately −0.5 V at duty cycle VOUT/VIN for driving inductor current. |
