Power Consumption onf LS1012A Development Boards

Hello, I am looking for design a board using the LS1012A ARM processor. I am looking at my power requirements and have a question that I hope someone can help me with. According to the documentation on the XFRWY-LS101A-PA Rev-B board the power consumption is 16W at 1A. Is there any information on how much current the board is consuming on the 0.9V, 1.35V, 1.8V and the 2.5V rails? I need this to determine if I will need a heat sink on my input regulator. My input voltage is 18V so I need to find a regulator that won't get too hot.

 

Thanks,

Joe
