LM2675M-ADJ from Texas Instruments, in a SOIC-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 | CB | input | Bootstrap capacitor connection node; connect 470nF capacitor between CB and VSW pins for high-side gate drive. |
| 2 | NC | unconnected | No connection pin. |
| 3 | NC | unconnected | No connection pin. |
| 4 | FB | input | Feedback sense input pin; connect to resistive divider midpoint for adjustable output setting or directly to output capacitor for fixed output. |
| 5 | ON/OFF | input | Enable input with 1.4V threshold at 25°C (0.8V to 2V over -40°C to 125°C range); high enables switching and low disables regulator with 50-100μA standby current. |
| 6 | GND | power_in | Ground connection to system ground and bypass capacitor grounds (CIN, COUT) with minimum trace length to CIN input. |
| 7 | VIN | power_in | Supply input accepting 6.5V to 40V connected to high-side FET collector with direct path to power source and short bypass to ground. |
| 8 | VSW | output | Internal high-side FET source pin (switch node) connected to inductor and external diode cathode. |
