LTC3786 Solution for Mosfet

Hello,

This is Sreenath, and I was going through the datasheet of "LTC3786", and I had a look for the high efficient boost converter application diagram using DRC attached.

So, the question is that, in the application diagram I saw that there are 2 MOSFET's present (RJK0305), so can I use one MOSFET in place of two ?

And will it encounter any problem?

Secondly, if I for instance want to change and use FDS7760A?

Actually I want my PCB board to be Higher efficient and less prone to heat, with Minimal components.

My Needs - 

7.4V to 8V input

24V Output at 3 ~ 5A

Application - 

Will be using it in a Sealed Audio Amplifier Enclosure.

Thank You!
