Low power design, choosing correct buck-boost converter for LiPo battery
This converter will work but there are much less complex converters available if you dont need all the extras the IC you mentioned is offering. Its also depending on your converter output requirements or rather the input requirements of the circuitry you want to supply. Also there are ICs available with a much smaller footprint which i guess is a factor in a portable application. Consider for example BD70522GUL from rohm, which is more than 10 times smaller. Also Keep in mind that LiPo batteries are not very happy about getting discharged too low.
