Hi This is Amar.
I want to design a AC-DC Adaptor by using LNK419.
And the voltage and current ratings are 14.0VDC and 3.8A operating range is 100-280VAC.
I want to use PQ26/20 Transformer for this design but in PXI Software there is the no information regarding the PQ cores.
And for this design the size of the adaptor is the main Key Point , So thats why am going to use this LNK419.
Can any one please suggest me the transformer calculations and the total design of the ckt.
