LM25085 Buck Converter

Other Parts Discussed in Thread: LM25085

I am having trouble getting my LM25085 chip to work correctly.  The pins in question are VCC and PGATE.  I cannot get VCC to raise from 0V, even when I try to force it.  PGATE sits around 3.5V instead of 12V.  Every other pin is right or about where it needs to be.  Attached is my circuit configuration.  It works great on PSPICE, but not in practice. 

Also, I don't think it's the soldering.  I did it at 225 degrees Celcius and tested each pin for connections and shorts.

Any help would be greatly appreciated
