TPS62122: Is this the right part?

Question from Customer:

Is the TPS62122 a good buck converter to use with ZF’s energy harvesters?

I’m looking for low energy loss:

·         Wide input range of the buck converter => smaller capacitor on the harvester => less energy in the cap when the buck converter turns off

·         High efficiency on the buck converter

·         Low power consumption of the buck converter
