I designed a buck converter on breadboard as shown in the picture. I am applying PWM from my microcontroller. I am not sure why this circuit is not working, I have spent so much time on it. Is there any problem with the connections? Or have I picked the right MOSFET and MOSFET driver? The MOSFET is N-type and the MOSFET driver is low- and high-side compatible. How do I know if the MOSFET driver is working as high-side or low-side? I guess PWM input from microcontroller is not a problem as I have tested it with a signal generator also.
