I see that you have both a UCC3817 and UCC3817A device which should I use?

For all new designs the UCC3817A and the UCC3818/9A device are recommended for new designs. These devices have a more robust gate driver and require less gate drive impedance to limit the gate driver current. The following link will bring you to an applications note that describes the differences. http://www.ti.com/general/docs/lit/getliterature.tsp?literatureNumber=slua294&fileType=pdf
