Steve's schematic can apply the TC4422 chip

[VNTC]

I had trouble with the GDT signal(signal ripples) for half a year.
Finally, I found the reason is that the UCC2732x driver chip (China’s product) has 3 pin does not work as enable pin.(no function pin)
The way to fix this problem is: use this schematic below

ChipTC4422 can work up to 18VCC so they provide more power to drive the GDT.
