LM2671M-5.0 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 pin requiring 100-nF capacitor connection from CB to VSW for high-side gate drive. |
| 2 | SS | input | Soft-start pin for output voltage ramp control; connect capacitor to GND or leave floating if not used. |
| 3 | SYNC | input | Frequency synchronization input operating at 260-kHz internal oscillator frequency when left open-circuited. |
| 4 | FB | input | Feedback sense input connected to output capacitor for fixed versions or feedback divider midpoint for adjustable versions. |
| 5 | ON/OFF | input | Enable input; voltage above 1.4 V enables switching while below 1.4 V enters shutdown mode with typical 50 µA standby current. |
| 6 | GND | power_in | Power ground connection to system ground and capacitor grounds with minimum path length from input capacitor CIN. |
| 7 | VIN | power_in | Supply input to high-side FET collector; connect to power supply and input bypass capacitor CIN with minimum path length, input voltage range 6.5 V to 40 V. |
| 8 | VSW | output | Source pin of internal high-side DMOS switch operating as switching node connected to load inductor and external diode cathode. |
