Hello Expert,
I observed unstable switching waveform as you can see below.
There is extremely short pulse as like as few ten ns.
This waveform is observed when I changed FB resistor network and load resistance from default file to achieve 3.3V 1A our as below.
Would you tell me why this issue happened and how to fix it?
I confirmed same condition at SIMPLIS just in case and result is stable as I expected.
Best regards,
