any ic is available for ZVT only that too with boost converter,i require it separately, This is for implementing ZVT on Interleaved boost converter.
Can you take a look at UCC28060 to see if it is ok for your applications?
The UCC28060 is not a ZVT boost controller. It is a quasi resonant interleaved PFC controller and not ZVT. Not shore how he would use this in a ZVT application.
There was a UC3855/A for ZVT PFC boost. However, it is not an interleaved controller.
