what is the related patent to LYT 4 or LNK PH ?
would you explain this diagram ?
There are multiple PI patents that are implemented on LYT-4 and LNK-PH. However, I don't have the means to enumerate them all.
If you are looking for a specific PI patent, you can look in the patent database.
The attached diagram is the simplified block diagram of LNK-PH showing the logic and power blocks that make up the IC. The datasheet and app note provide einformation about how each pin works.
If there is a specific info you want answered, please let me know. Your questions are too broad for me to answer in details.
