LM2672MX-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 | input | Bootstrap capacitor connection for high-side driver; connect 100-nF capacitor between CB and VSW pins. |
| 2 | SS | input | Soft-start capacitor pin; connect capacitor to ground to control output voltage ramp or leave floating if feature not used. |
| 3 | SYNC | input | Synchronization input pin; if open-circuited, regulator operates at internal 260-kHz oscillator frequency. |
| 4 | FB | input | Feedback sense input pin; for adjustable output version, connect to feedback divider midpoint to set output voltage from 1.21 V to 37 V. |
| 5 | ON/OFF | input | Enable input with 1.4 V threshold; voltage less than 1.4 V disables regulator with 50-μA typical standby current, greater than 1.4 V enables, or leave open to enable. |
| 6 | GND | power_in | Power ground pin; connect to system ground and to ground pins of input and output capacitors. |
| 7 | VIN | power_in | Supply input pin to high-side FET collector; recommended operating voltage range is 6.5 V to 40 V. |
| 8 | VSW | output | Source pin of internal high-side FET switching node; connect to inductor and cathode of external Schottky catch diode. |
