LM22672QMRX-ADJ

Texas Instruments · DC-DC Converters · SO-8

LM22672QMRX-ADJ from Texas Instruments, in a SO-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 BOOT input Bootstrap input that provides the gate voltage for the high-side NFET.
2 SS input Soft-start input; a capacitor on this pin is used to increase the soft-start time.
3 RT/SYNC input Oscillator mode control input used to set the switching frequency or synchronize the oscillator to a system clock (see Frequency Adjustment and Synchronization section).
4 FB input Feedback input to the regulator.
5 EN input Enable input that controls regulator start-up and shutdown (see Precision Enable and UVLO section).
6 GND power_in System ground pin of the regulator (system common).
7 VIN power_in Supply input to the regulator; recommended VIN supply range is 4.5 V to 42 V and the VIN-to-GND absolute maximum is 43 V.
8 SW output Switching output of the regulator; SW to GND DC absolute maximum is -5 V to VIN, with a -10 V limit for pulses up to 50 ns.
