How to remove the noise from the transformer in TNY(POWER INTEGRATION) based power supply?
Start with Power Integrations app note AN24 - available at www.powerint.com
I was curious. So I tried searching for "AN-24"...:
http://www.powerint.com/product-docs/24
And tried...:
http://www.powerint.com/en/product-docs/24
And failed...
It seemed funny - the messages are empty.
Then I tried more... for "AN24"... and succeeded:

It seems a bit complicated to find the necessary stuff there. I found one more discussion here:
http://www.powerint.com/ko/forum/power-supply-design/audible-noise-ccim
Try searching for "noise" there, and you get lots of other stuff to get yourself lost in. Go, and dig...
The talk in AN24 (AN-24) seems to be about audible noise. Other topics on that site also speak about electrical noise.
... Not that I am using their products... So I can't really comment on content.
I just poked my nose into it.
