I found the reference design in the data sheet but noticed that it is 
different than all of the other designs in that it has only 1 inductor and 
two shottky diodes. Did you build it that way and it worked? If so I'll use 
it like you did with minor tweaks to get the voltage I want out of it. If 
its really a typo and D2 is really L2 like it is in the other designs I'll 
fix that when I lay it out.
