Maximum power by Buck converter

Hello to all. I want to make a buck converter Vin:70v , Vout:30~65v, Iout=0~7A. my question that can I make a buck converter by this properties, I mean is this possible? Another question, What is the maximum power that I can make by a converter like buck, if it is low, please tell me why? Very thank you.

That is certainly possible, but a 450 Watt converter requires high power components and excellent circuit design and construction techniques.

Not an Arduino-type project.

You have been asking this question for almost a year now, spread over dozens of threads and hundreds of posts. Buy one, and get on with your life. Leo..

Entirely possible, but a tough job, that’s a very demanding spec. Not really Arduino-related though.
