Hi,
Would certainly be interesting to scope the Mosfet Drain voltage ... I would not be surprised it goes much over the 100 v rating of the '530.
1mH is a BIG inductor...
You did not tell about your diode ... very fast recovery, I hope !
a series resistor in the gate will lengthen the switching time, and may be hide the problem.
but also increase losses ...
some simulation could help to choose the best components match ...
May be also too close OFF/ON "togglings" of your device ( mains failure i.e. ) can generate some Mosfets destroyed ... my computer inverter supply did it to me once my finger slipped on the ON switch ...

Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

IF there is the word "Problem" in your question ...
certainly the answer is " RTFM " or " RTFDataSheet " !!!
