Hi,,
The attached synch rect cct involving LTC3723-1 and LTC3901 does not work right at all.
There is too much ringing between CDS of the synch FET and the txformer Llk. Thence too much snubber losses
This isnt really solvable with realistic workarounds.
How are these synch rects expected to be used?
I have unhooked the synch rects in the attached, but they are easily re-connected , shoudl you wish to do so.
