LM22670QTJ-ADJ

Texas Instruments · DC-DC Converters · TO-263-7

LM22670QTJ-ADJ from Texas Instruments, in a TO-263-7. 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 SW output Switching output of the regulator.
2 VIN power_in Supply input to the regulator.
3 BOOT input Bootstrap input that provides the gate voltage for the high-side NFET.
4 GND power_in Ground input to the regulator and the system ground pin.
5 RT/SYNC input Switching frequency adjustment and synchronization input, used to set the oscillator mode per the datasheet's oscillator mode control section.
6 FB input Feedback input to the regulator.
7 EN input Enable input used to control regulator start-up and shut-down, with precision enable and UVLO.
8 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
