Is it a single cell battery or multiple series cells? How much current are you driving it at?

It looks like the forward voltage will always be less than the battery voltage, so a buck converter only is needed.

You could use the TPS62090 with this app note: www.ti.com/.../slva451.pdf

Or a TPS630xx device (TPS63010 for example) with this app note: www.ti.com/.../slva419b.pdf
