LM2675MX-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 | CB | output | Bootstrap capacitor connection pin for high-side gate driver; connect a high-quality 470nF 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 midpoint of feedback voltage divider (adjustable version) or directly to output capacitor (fixed version) to set output voltage. |
| 5 | ON/OFF | input | Enable input for voltage regulator; high voltage = enabled, low voltage = shutdown; pull high or leave open to enable regulator. |
| 6 | GND | power_in | Power supply ground pin; connect to system ground and to ground leads of CIN and COUT capacitors; keep distance to CIN as short as possible. |
| 7 | VIN | power_in | Power supply input pin, rated 6.5V to 40V; connect to power source and input bypass capacitor CIN with short leads. |
| 8 | VSW | output | Internal high-side FET source pin and switching node; connect to inductor and external diode cathode for buck converter operation. |
