Hi,
I am currently running with the design as attached, but with a 7.6A gate driver in line with the MOSFET, it seems that when I am running this at 333KHz (my desired switching frequency) there is a loud hissing noise and the DR output is jittering al over the place. When I reduce this down to 283Khz its fine. Any idea's as to why?
