Every time MOSFET on and off, there is an overshoot wave of 1V. Now I am trying to step down 17V to 5V. My switching frequency is 133KHz. As I said, overshoot wave 1V synchronize with noises on 5V supply line on top of 100mV noise itself. This noise give problems to my circuit which using that 5V supply. So now according to your article my understanding is if I increase the switching frequency, that might solve the problem? I will try that. By the way I am using 390uH inductor. Hi,
