LM22670QMR-5.0

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

LM22670QMR-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; the pin does function as a thermal conductor.
3 RT/SYNC input Switching frequency adjustment and synchronization input: a single resistor sets the frequency from 200 kHz to 1 MHz (default 500 kHz), and the internal oscillator can synchronize to a system clock or another regulator.
4 FB input Feedback input to the regulator; the FB pin voltage is rated from -0.5 V to 7 V.
5 EN input Precision enable input that controls regulator start-up, shut-down and UVLO; the EN pin voltage is rated from -0.5 V to 6 V.
6 GND power_in Ground input to the regulator and the system ground pin.
7 VIN power_in Supply input to the regulator; recommended supply range is 4.5 V to 42 V, with an absolute maximum of 43 V to GND.
8 SW output Switching output of the regulator; DC SW-to-GND is limited to -5 V to VIN, with a -10 V extended limit for pulses up to 50 ns.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
