Use TL072 , IR2183 , IRF1010
The 10nF capacitor set the soft-start time.
The 3nF capacitors simulate the internal gate capacity of each mosfet.
Gate resistors should be from 4.7 to 10 ohm

PWM = 5/(29.1-0.76) = 17.63% -> 20%
Pout = 5*20 = 100W
Pin = 30*20*0.2= 120W
n = Pout/Pin = 83% in extreme conditions
