I have a transformer design for LNK6404D.
Looking into expanding it's usage for different products but there are some thing I would like to address.
1. Current design has barely audible acoustic noise.
I'm planning to use it in semi-open enclosures so it is first thing to fix. Changing BM_TARGET from 1800 to 1500 seems to help in reducing sound to almost non-existant.
Are there any other parameters that could be looked into to reduce acoustic noise?
2. Tight fit due to TIW secondary winding
For transformer test samples with reduced BM_TARGET suggested secondary windings with TIW cannot be fit to EF12.6 transformer.
What are negatives of reducing TIW wire gauge other than increased loss due to higher resistance and lower efficiency?
