TOPSwitch-JX - Design Support

We are currently working on a new project in which we use the component TOP264-271-DIP-E-12B.
The circuit diagram and all the necessary data have been created using the PiExpert software you have provided (see appendix).
In general, it is about developing a switching power supply with an output power of 5V / 4A.

We are currently in the layout design phase and would need support.
We would be delighted if your technicians were able to take a quick look at the attached layout and give us relevant feedback (regarding EMC, performance and AC / DC Layout Guidelines).
If you need further data or information, we will gladly supply it.

We hope you can help us here.
