Hi,
We couldn't get the vendor for the LLC transformer(EEL25.4 core and EEL25 Vertical 3 chamber Bobbin).
Shall we use the below EF25 core and the EF25 3 section horizondal bobbin as a alternate for the LLC transformer?
Kindly suggest.

EF25 is a little small and could resutls in higher temp in higher ambient. EEL25 on the RDK292 design has similar thermal issue.

suggest to use ETD34 for integrated magnetics. or for seperated leakage inductor design, try EER28  as main transformer.
