Driving parallel MOSFETs (IRF540) with IRS2092
It will be able to drive parallel MOSFETs because they are being used in their triode region but, take into account what the application note says here: -

So, if you choose two parallel MOSFETs you should ensure that the total combined gate charge does not exceed the limitations implied in the top paragraph.
You might also be sensible to track down what AN-1070 is telling you: -

Enjoy the read.
