LM2672MX-ADJ

Texas Instruments · DC-DC Converters · SOIC-8

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.
