TPS63002: High Current Draw!

Part Number: TPS63002

I have a Microcontroller circuit that can work off of 5v or 3.3v. The power supply section is using the parts in your PDF typical application schematic. I'am  powering unit with 2 aa batteries. Problem is when using  63002 device I only get 3.1v out and input current is 900ma. The circuit only draws 8 ma. I can replace the TPS63002 with a TPS 63001 3.3v version and all works fine! I have my 3.3v and 12ma of current.

Any Ideas?
