LM2594MX-5.0 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 | Sense input that measures the regulated output voltage to complete the feedback loop. |
| 5 | ON/OFF | input | Logic-level control input that enables regulator when pulled below 1.3V and disables when pulled above 1.3V (maximum 25V), reducing quiescent current to 80μA. |
| 6 | Ground | power_in | Circuit ground reference, 0V potential. |
| 7 | +VIN | power_in | Positive input supply for IC switching regulator, 4.5V to 40V for LM2594, requiring low-ESR bypass capacitor to minimize voltage transients and supply switching currents. |
| 8 | Output | output | Internal switch with output voltage switching between (+VIN−VSAT) and −0.5V at duty cycle VOUT/VIN; PCB copper area must be minimized for EMI control. |
