LM2674MX-5.0-TP from TECH PUBLIC, in a SOP-8. 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 | NC | unconnected | Not connected. |
| 2 | NC | unconnected | Not connected. |
| 3 | NC | unconnected | Not connected. |
| 4 | FB | input | Feedback pin that senses the regulated output voltage to complete the feedback loop. |
| 5 | ON/OFF | input | Allows the switching regulator circuit to be shut down using logic level signals; input voltage range is -0.3 V to +VIN. |
| 6 | GND | power_in | Circuit ground. |
| 7 | VIN | power_in | Positive input supply for the IC switching regulator (absolute maximum 45 V); a suitable input bypass capacitor must be present at this pin to minimize voltage transients and supply the switching currents. |
| 8 | SW | output | Internal switch output whose voltage swings between +VIN minus VSAT and approximately -0.5 V; keep the PC board copper area on this pin to a minimum to limit coupling to sensitive circuitry. |
