bq25504 - Buck-Boost Topology?

Is there a similar chip suitable for energy harvesting that can run a buck-boost architecture?  I have not spent much time looking this chip over yet, but is this chip capable of driving a buck-boost as is?  I have a unique energy harvesting application that has an output voltage ranging somewhere between the typical low voltage EM, solar, etc. and the high voltage piezoelectrics.  Depending on the amount of energy available at a given time, the output voltage can be higher or lower than desired for charging a 3.3V energy cell for example.  Any advice would be appreciated.  Thanks.
