LMG3410R070: Buck-Boost Inductor Design

Part Number: LMG3410R070

We use ENR201610F-100M for the buck-boost inductor. We find the VNEG will be no output when we re-soldering GaN or Inductor. May I know how to select the inductor? Is the ENR201610F not suitable for this design?

BR,

Gary

    Hi Gary,

    This inductor looks fine for the buck-boost inductor for the LMG3410R070. The inductor we use on our evaluation module is the 74404020100 from Würth Elektronik and it has nearly the same ratings. Can you share the schematic and layout you are using and I can check for anything else that may be causing this issue.

    Best,
