Hello Mr.Supat Matura,
Did you already take a look at the DER-337?
It looks perfect for you.
Hi Sumat,
Thanks for using PI products.
For your design, you can use LinkSwitch-PH. The closest available DER that I found in the database is DER-256 but it's isolated. You can convert the design to buck-boost for non-isolated design.Please use PIXLS spreadsheet which is part of PIExpert Suite to make preliminary design and I suggest that you contact the local FAE to support your project. The address of the nearest Sales Office is given below:
Let me know if you trouble contacting them.
