switching loss
I am doing 40W boost converter LED driver.
V(in) = 9V
V(out) = ~30V
I(out) = 1.3A
Here is the FET current

Here is the schematic:

I have a choice between N MOSFET’s for the switch:-
…….either IRLR3110 from irf.com
………..or IPD079N06L3 from Infineon
…..which one of these will give the lowest switching losses?
