LM22679TJE-5.0

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

LM22679TJE-5.0 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; the absolute maximum SW-to-GND rating is -5 V DC up to VIN, with a -10 V limit for pulses of up to 50 ns.
2 VIN power_in Supply input to the regulator; the recommended VIN range is 4.5 V to 42 V, and the absolute maximum VIN-to-GND rating is 43 V.
3 BOOT input Bootstrap input that provides the gate voltage for the high-side NFET; the absolute maximum boot pin voltage is VSW + 7 V.
4 GND power_in Ground input to the regulator and system common; connect to the system ground.
5 IADJ input Current-limit adjust input; a resistor between this pin and GND sets the current-limit threshold, the pin can be left floating for the internal default, and the absolute maximum pin voltage is -0.5 V to 7 V.
6 FB input Feedback input to the regulator; the absolute maximum FB pin voltage is -0.5 V to 7 V.
7 SS output Soft-start pin used to increase the soft-start time (see section 7.3.2); the absolute maximum SS pin voltage is -0.5 V to 7 V.
8 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
