Mr. John.
The voltage between LSENSE and LCOM of inductor coil, frequency and
I measured the voltage and frequency between LREF and LCOM.
Three different waveforms were measured between LSENSE and COM and between LREF and LCOM.
The frequency was C:80PF, L:23.67μH (one side), and I was expecting 3.7MHz.
The frequency was C:80PF and L:23.67μH (one side), which is more than one order of magnitude different from the expected 3.7MHz.

From this phenomenon, it is conceivable that the two inductor coils
This phenomenon may mean that the two inductor coils are not connected correctly?
LSENSE coil on a universal board
LREF coil on the back side
That's all. Please let me know what you think.
Thank you for your cooperation.
