About MC33816 Vboost

I used the MC33816 IDE build the code for MC33816, but however I changed the Vboost voltage, from 24V to 65V. The Vboost always up to almost 80V, then the chip be broken. The mean is I can't control it. Can you help me? 

Thanks!

I also encountered the same problem, I can't control the Vboost,so I had to use a voltage regulator to protect the MC33816 from damage。

Does anyone know of a solution to this problem?

Which kind of board do you test on? EVB or your own design board?

Suggest you test in EVB firstly,even if the default setting the Vboost can't up to 80V because of the maximum value is about 72V.
