Both these device can be used to be power upAM335x. Preferred device for DDr2 is TPS65910.

I2C internal is not needed if you dont want to do any software transaction but it is needed for all software.

Both are suitable. The TPS65910 offers more features like the I2C communication you mentioned. The TPS650250 is the lower cost power solution but, some of the features are not offered or supported.

The 1.8V rail for DDR2 is supported by both.
