LM22672MR-ADJ

Texas Instruments · DC-DC Converters · SO-8

LM22672MR-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 providing gate voltage for high-side NFET; absolute maximum voltage VSW + 7V.
2 SS input Soft-start input for controlling soft-start time; absolute maximum pin voltage 7V.
3 RT/SYNC input Oscillator frequency adjust and synchronization input; absolute maximum pin voltage 7V.
4 FB input Feedback input for output voltage setting; absolute maximum pin voltage 7V.
5 EN input Precision enable input with UVLO for regulator start-up and shutdown control; absolute maximum pin voltage 6V.
6 GND power_in Ground reference and system common; connect to system ground.
7 VIN power_in Supply input with recommended operating range 4.5V to 42V and absolute maximum 43V.
8 SW output High-side switch output with voltage range -5V to VIN; provides switching function for step-down regulation.
