Hello!

I'm trying to figure out how to use two pc817 optocoupler's as a gate driver for a IRFZ44N mosfet. My senior design team is using the mosfet as a switch in our buck converter/solar charge controller that we are designing. The solar panel has between 17-21v and supplies 10W going to a 12v deep cycle marine battery. The trouble i am having is finding an electrical schematic that shows the configuration of (Arduino/pc817/mosfet) so that we can use the mosfet as a switch. I appreciate your time and any information that you may have.

Regards,

Jack

Why are you using the optoisolator in the first place? Isolation? If that’s the objective, then ignore this.

With a logic level MOSFET, such as an IRLZ44N, you can drive a load directly.
