Does one program UCD3138 through the PMBUS data &clk ports?
In such a case, do we have to get a license for using PMBUS if it is not in the public domain?
In a related matter: in TIDUCT9 document, LLC stage is required to have 62.2 uH control freq changing over 150 kHz to 250 kHZ( if I recall)
But in UCD3138 LLC design per tidrn80/82 0r 83, switching sweeps over 200kHz to 750 kHz and Lr is only 2.6 uH
Why such a huge difference?
Would there be any spreadsheet calculations where we can get properly analyzed values for such parameters Lr, Cr , xmfr ratio, ...etc?
