Hello, I am designing a flyback converter with an input voltage of 500VDC to 800VDC and an output voltage of 15V/2A. 

Among several products, we plan to design using INN3649C that meets the rating conditions.
Please provide design references that are identical to my specifications or a design that matches my system specifications.
The most important consideration is stability. Price and power density are issues to be discussed later. thank you
