Part Number: UCC2808A-1
Is it possible to achieve a circuit of Fig.2 of ucc2808 data seat?The input voltage area which is 72V from 36V by Push - Pull system, can it correspond?

I'm seeing rebesion SLUS456D of a dataseat.
The circuit which is being asked is attached.

In reply to John Griffin1:
The push pull can be designed for this wide voltage range.
For example if the output duty cycle is 90% at 36V (corresponding to 45% duty cycle on each gate drive) then the required output duty cycle will be 45% at 72V(corresponding to 22.5% duty cycle on each gate drive)Does that make sense? Of course it is always difficult to design a power supply with a wide input range but it is possible to do so with the right care and attention to details
