LT8300 12-50Vin to 5V 1W output

Category: Software
Product Number: LT8300


i need to design a small isolated power supply by using LT8300. I need am small amount of power, max 1W at 5Vout. The problem is the input that span from 12V to 50Vin (spike 70V).

By using the spreadsheet provided by LTPowerCAD i get an error on Qpk current that is too high.

Is ther any solution with the LT8300 or i need to use another controller?
