LMG3410R050: Buck-Boost Converter Switching

Hi Gary,

The buck boost converter doesn't have a set frequency. It restarts the switching cycle once the current in the inductor hits 0A. So the rise time and fall time of the inductor current is affected by the inductor value used. For a 22uH we see ~500kHz switching frequency, you can scale this to a 10uH inductor which should be ~1.1MHz.

Best,
