I've designed a buck converter with a 6V input. It is running at 60% duty cycle & is carrying abt 1.5A current.
I'm using a IRL3103 mosfet as my switch. When I test the gating signal to the switch, seperately when the switch is not in the buck circuit, I get a good switching waveform, however when I set it up in the buck converter the gating waveforms are highly distorted with a lot of noise. However the o/p is still abt 3.3V as expected. I want to eliminate this noise, & figure out why it is coming in the first place.
TIA
