Part Number: UCC28950

I am trying to make a variable power supply using UCC28950.

I cannot set the output voltage above 50V using WEBENCH®.

Any reason why?

Is it possible to manufacture with the following specifications?

・INPUT: 390-410V

・OUTPUT: 30-130V 9A

Please let me know if you have any problems.

Also, if there is an application example close to this specification, please let me know.

Thanks

Hello,

The UCC28950 should work for your application. Sorry about the limitation in Webex.

The following link will bring you to an application note that describes how to use the UCC28950 in a phase shifted full bridge. Inside the application note there is a link to an excel design tool, that should help aid you in your design process.
