How to operate bq25570 Battery Charger Evaluation Module as a booster

I have a power source that can give me around 0.9 ~ 1 V and 900uA. I would like to use the bq25570 Battery Charger Evaluation Module to give an output of 1.8 V. I would like to attach a capacitor to discharge the current at 1.8 V. I looked at the Manual, However, It would discuss how to set it up as a buck converter.


How can I set it up to increase my voltage while charging the capacitor? If I can not boost my voltage, how can I use it to harvest energy from the input while outputting at the same voltage?
