LM22672MR-5.0

Texas Instruments · DC-DC Converters · SO-8

LM22672MR-5.0 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 drive voltage for the high-side NFET; BOOT pin voltage is limited to VSW + 7 V (absolute maximum).
2 SS input Soft-start input used to increase the soft-start time; SS/RT/SYNC pin voltage is limited to -0.5 V to 7 V (absolute maximum).
3 RT/SYNC input Oscillator mode control input for frequency adjustment and synchronization; SS/RT/SYNC pin voltage is limited to -0.5 V to 7 V (absolute maximum).
4 FB input Feedback input to the regulator; FB pin voltage is limited to -0.5 V to 7 V (absolute maximum).
5 EN input Precision enable input used to control regulator start-up and shutdown; EN pin voltage is limited to -0.5 V to 6 V (absolute maximum).
6 GND power_in System ground pin for the regulator, which serves as the system common.
7 VIN power_in Supply input to the regulator; recommended supply voltage is 4.5 V to 42 V, with 43 V as the VIN to GND absolute maximum.
8 SW output Switching output of the regulator; SW to GND is limited to -5 V to VIN in DC, with a -10 V extended limit for pulses up to 50 ns.
