Currently there is no adobe application that can convert a file which can be used in iPad, however, it will be soon be available. I think the following link might help you in answering your question.
This link talk about the application that can convert the file to epub format which can be used in various devices such as Sony eReader, nook, iPhone etc.
I hope this might be helpful to you.
BlueFire Reader works on the iPad and the iPhone, iPod systems. It is not as convenient as one might want, but there are the instructions posted on the website.
Also Overdrive now has an App for the iPhone and say they will have one for the iPad shortly. It provides for direct downloads from a library and is OK on the iPad but not as good as BlueFire yet.
