I am simulating a boost converter in ltspice.
vin=3V, vout_bst=12V, ideal inductor, capacitor, diode and voltage source. When I use an ideal switch, raising the frequency doesn't affect the output voltage but when I use MOSFET transistor BSZ036NE2LS the voltage drops when I raise the frequency.
*The highest is @100kHz, the lowest @1MHz (100kHz steps)
I understand the transistor causes it but I didn't find a frequency restriction in it's datasheet and I don't know how to explain this derating.
edit: Rload=17.142 (I wanted for the simulation Iload=0.7A)
