Question three
Same buck converter. VIN=12 V, VOUT=1.2 V, IOUT=20 A, fsw=1 Mz. If the Td(on)=Td(off)= 2.5 ns, calculate the both eGaN FET and MOSFET body diode power loss. We’re still at 25 C.
A. MOSFET: 0.07 W eGaN FET: 0.2 W
B. MOSFET: 0.14 W eGaN FET: 0.4 W
C. MOSFET: 1 W eGaN FET: 3 W
D. MOSFET: 0.19 W eGaN FET: 0.86 W
E. MOSFET: 0.034 W eGaN FET: 0.04 W
