LM22672QMR-ADJ

Texas Instruments · DC-DC Converters · SO-8

LM22672QMR-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; BOOT pin voltage is limited to VSW + 7 V.
2 SS input Soft-start input used to increase the soft-start time; SS pin voltage is limited to -0.5 V to 7 V.
3 RT/SYNC input Oscillator mode control input used to set the switching frequency (200 kHz to 1 MHz via a single resistor) or to synchronize the internal oscillator to a system clock.
4 FB input Feedback input to the regulator; FB pin voltage is limited to -0.5 V to 7 V.
5 EN input Precision enable input that controls regulator start-up and shutdown and system power sequencing; EN pin voltage is limited to -0.5 V to 6 V.
6 GND power_in System ground pin for the regulator and the common reference for all other pins.
7 VIN power_in Supply input to the regulator; recommended VIN is 4.5 V to 42 V, with an absolute maximum of 43 V to GND.
8 SW output Switching output of the regulator; SW to GND is limited to -5 V DC (extended to -10 V for pulses up to 50 ns) and to VIN.
