LM2672M-ADJ

Texas Instruments · DC-DC Converters · SOIC-8

LM2672M-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 passive Boot-strap capacitor connection for the high-side driver; connect a high quality 100-nF capacitor from CB to the VSW pin.
2 SS input Soft-start capacitor pin; connect a capacitor from this pin to GND to control the output voltage ramp, or leave it floating if the feature is not desired.
3 SYNC input Allows control of the switching clock frequency; if left open-circuited the regulator switches at the internal oscillator frequency, typically 260 kHz.
4 FB input Feedback sense input; connect to the midpoint of the feedback divider to set VOUT for the ADJ version.
5 ON/OFF input Enable input to the regulator where high = ON and low = OFF; pull high or float to enable, with ON/OFF pin voltage rated -0.1 V to 6 V.
6 GND power_in Power ground pin to be connected to system ground; the path to CIN must be as short as possible.
7 VIN power_in Supply input pin to the collector of the high-side FET; recommended supply voltage range is 6.5 V to 40 V.
8 VSW output Source pin of the internal high-side FET and switching node that connects to the inductor and the external diode cathode; switch voltage to ground limited to -1 V minimum.
