I want to make a multiphase SMPS with a variable output voltage from 2V 
to 10V.  The current through this supply would be 4A-20A. (it's attached 
to a passive load).  The load, however, doesn't like ripple current, so 
I thought that a two-phase SMPS would be a good idea.  Even some of the 
4-phase SMPSes look nice until I see that they only go up to 3.3V

The TPS40090 was like that.  It looks good to me except for the obvious 
problem with the 3.3V limit.  I could likely fake it out, but the 
question is whether it's worth doing that.
Any suggestions on how to build an adjustible 2-10V multi-phase SMPS?

Thanks,
Brendan
