the design of a ferrite transformer is a trade-off, there isn't a direct relation between core cross section area and output power. A good starting point could be the application notes that you can find at this link **broken link removed**
These application note are written by Colonel Wm. T. McLyman, you can buy his books at http://www.ejbloom.com/
