LM22670QMRE-5.0

Texas Instruments · DC-DC Converters · SO-8

LM22670QMRE-5.0 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 gate drive voltage for high-side N-channel MOSFET with absolute maximum voltage rating VSW + 7 V.
2 NC unconnected Not electrically connected within the chip; functions as thermal conductor.
3 RT/SYNC input Switching frequency adjustment and synchronization input for oscillator mode control with voltage rating -0.5 V to 7 V.
4 FB input Feedback input for voltage regulation with voltage rating -0.5 V to 7 V.
5 EN input Enable input for regulator startup and shutdown control with voltage rating -0.5 V to 6 V.
6 GND power_in System ground and power return connection for the regulator.
7 VIN power_in Supply input voltage with recommended operating range 4.5 V to 42 V and absolute maximum rating 43 V.
8 SW output Switching output with DC voltage range -5 V to VIN and extended negative pulse limit -10 V for 50 ns maximum.
