Can someone explain to me why there is a 500nS delay between the sync pulse going low and the Gate drive going high? See plot below. I need a shorter dead-time and the propagation delay seems to be the dominant factor. The current oscillator set up is as follows:
Ct= 470pF
Rt=7k ohm
The oscillator calculation says I should be getting a 68nS dead time, of which I'm getting 240nS dead time pulse, which does not include this turn on delay. Any help to minimize this turn on propagation delay would be appreciated.
The IC states a 500KHz operation, could I be to close to that, or off in the weeds where none of the equations work?
The oscillator in plot below is running at 450KHz, and my supply is running at 225KHz, is the 500KHz max oscillator frequency or supply frequency?
IF this part doesn't like the higher frequencies, Is there a device that could be more suitable for higher frequency operation that is pin compatible?
Thanks in advanced for you help
