LM22670QMRX-5.0

Texas Instruments · DC-DC Converters · SOIC-8-EP

LM22670QMRX-5.0 from Texas Instruments, in a SOIC-8-EP. 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.
2 NC unconnected Not connected inside the chip, but the pin functions as a thermal conductor to the PCB.
3 RT/SYNC input Switching frequency adjustment and synchronization input; a single external resistor sets the frequency from 200 kHz to 1 MHz, and the pin also controls oscillator mode.
4 FB input Feedback input to the regulator.
5 EN input Enable input used to control regulator start-up and shut-down through the precision enable and UVLO function.
6 GND power_in Ground input to the regulator and system ground pin.
7 VIN power_in Supply input to the regulator.
8 SW output Switching output of the regulator.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
