Hi Sanoki-san,

Section 4.5.16 shows the overall system current depending on the mode and supply, otherwise you would have to add up all of the applicable ground currents that are still supplied.

Hi Rick,

Sorry for my delayed response.
Now I'm supporting TPS80032 and find large leakage issue from few samples on customer's board. I'd like to send you customer's schematic, so can you contact me directly? Please find my email address in profile.

Best Regards,
Sonoki
