UCC24624: Can I use this in active clamp forward converter?

Part Number: UCC24624

I'm supposed to use a synchronous rectifier driver for the active clamp forward converter design, in which I'm currently working in.

Can I use this IC (UCC246264) for the synchronous rectification process of active clamp forward topology?

    Hi ,

    I have reached out to one of my teammates regarding this. Here is his response: 

    " I don’t know for sure since it's not validated on the hardware, but I think the -624 can be used in ACFwd…  I don’t see anything in the DS that would prevent it.

    My biggest concern is what happens when duty cycle approaches zero.  There is a minimum on time once either channel is triggered. So that may be the show stopper if the ACFwd can go to near-0 duty, but the SR can’t and stays on too long. It is supposed to have anti-cross conduction to prevent this.  Not sure what’ll happen when the clamp is on but it’s SR is suppressed by the anti-X circuit. "

    Regards
