I'm designing a buck converter based on TL494. And I have to drive high side mosfet, i want to use a gate drive transformer, switched by totem pole driver. The problem is that slopes of signal coming out at collector are (i think) very bad. (>100ns) I want to drive mosfet with slopes <50ns, and signal will get only worse in transformer etc. Problem is really visible with low duty cycle (signal has almost triangle shape). Also tried with TL494 on high side, and R3 on low side. I can post scope images. I am thinking right? Could i get better slopes from TL494?
