This is for a motor controller. So the supply voltage for the DC motor can change (using a variable power supply). I'm thinking of a range of 12V to 40V(MAX), max current is 4A.
Select MOSFET driver with average current greater than (sw. Freq. * Qg) of MOSFET....and which will provide peak gate current to the MOSFET..
Where as IRF530 Qg is not too high....you have plenty of options...
Best of Luck....
