Is it necessary to use Gate Driver for Mosfet Switching?

Hi I am trying to build a buck converter to drive a big DC Motor. It will draw nearly 15 A from the rectified threephase source.

I will construct a buck converter and make the switching thing with the arduino nano, I will just use PWM with different duty cycles to on-off (switch) the MOSFET to use buck converter

Is it necessary to use a gate driver or not?

The MOSFET I will use is this : IXFH30N60X IXFH30N60X IXYS | Discrete Semiconductor Products | DigiKey

it looks like that particular MOSFET requires more than 5V (Vgs) to fully turn-on and in that case you need a driver.

A "logic level" MOSFET in a Low-side Driver only needs a couple of resistors and a flyback diode. A high-side 15V driver also needs some additional circuitry.

Yes. The 5V from the arduino is to low. Make a driver with a transistor @12V. 5V with LTC1157 is with 8,8V to low to use.
