LM2675MX-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 | CB | output | Bootstrap capacitor connection for high-side gate driver; connect 470 nF capacitor between CB and VSW pins. |
| 2 | NC | unconnected | No connection pin. |
| 3 | NC | unconnected | No connection pin. |
| 4 | FB | input | Feedback detection input pin; connect to voltage divider midpoint to program output voltage for adjustable version, or directly to output capacitor for fixed version. |
| 5 | ON/OFF | input | Enable input for voltage regulator; high level enables, low level disables; pull high or leave floating to enable regulator. |
| 6 | GND | power_in | Ground pin; connect to system ground and bypass capacitor grounds; minimize connection length to input bypass capacitor. |
| 7 | VIN | power_in | Unregulated power supply input (6.5 V to 40 V operating range); connect to positive supply and input bypass capacitor CIN; minimize connection length. |
| 8 | VSW | output | Internal high-side FET source pin (switch node); connect to output inductor and external Schottky diode cathode. |
