Hi Fandy,

Sorry about the delay in response because of some thread assignment issues.

Datasheet shows efficiency of the boost because its output feeds other circuits and supplies within TPS65150 and its efficiency contributes the most to overall efficiency of the device. Picture below shows how to get overall efficiency.

Kind Regards,

Liaqat
