LM2671M-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 for high-side driver; connect a high-quality 100-nF capacitor from CB to VSW pin. |
| 2 | SS | input | Soft-start input pin; connect a capacitor from this pin to GND to control the output voltage ramp, or leave floating if not desired. |
| 3 | SYNC | input | Synchronization input pin allowing control of switching clock frequency at typically 260 kHz internal oscillator frequency when left open-circuited. |
| 4 | FB | input | Feedback sense input pin; connect to the midpoint of feedback divider to set VOUT for ADJ version or directly to output capacitor for fixed versions. |
| 5 | ON/OFF | input | Enable input to the voltage regulator where High = ON and low = OFF; pull this pin high or float to enable the regulator. |
| 6 | GND | power_in | Power ground pin; connect to system ground and ground pins of CIN and COUT; path to CIN must be as short as possible. |
| 7 | VIN | power_in | Supply input pin connected to collector of high-side FET; connect to power supply with input bypass capacitors CIN and path as short as possible. |
| 8 | VSW | output | Source pin of the internal high-side FET and switching node; attach this pin to an inductor and the cathode of the external diode. |
