LM22680MRE-ADJ

Texas Instruments · DC-DC Converters · SO-8

LM22680MRE-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 the gate voltage for the high-side N-channel MOSFET.
2 SS output Soft-start output pin used to increase soft-start time with external capacitor (100 nF to 1 µF).
3 RT/SYNC input Oscillator mode control pin for adjusting switching frequency from 200 kHz to 1 MHz or enabling external clock synchronization.
4 FB input Feedback input to the regulator; voltage is compared to internal 1.285 V reference.
5 EN input Enable pin with precision control and UVLO; regulator turns on above 2.2 V (typ) and off below 1.6 V (typ).
6 GND power_in System ground connection.
7 VIN power_in Input voltage supply pin with operating range of 4.5 V to 42 V.
8 SW output Switching output of the regulator providing rectangular waveform from 0 V to VIN.
