As Sgt had explained the study of gate charge between the Z46 and 540 tells me that the Z46 requires more time to turn on at a given gate voltage as the capacitance is twice that of 540.
Which will result in higher power dissipation than the 540.
So I assume that if the I can get the DC voltage at the converter output the FET's are working at the slight heat is due to the FET turn on delay caused by increased by gate capacitance.
Other than that there is no other reason for the slight heat up as the Power handling are almost same.
I am going to seam heat sinking will handle the warm up.
Am I right Sgt?
