MP2313 - efficiency for very low output current

Good Morning,

I’d like to ask why is the efficiency if MP2313 shown only for output current down to 10mA; what happens for lower currents?

I’m using the MP2313 to generate the 3.3V digital power of my system, which is battery-powered (2s1p Li-Ions battery pack, 7.2V nominal voltage, usable voltage range 6-8.2V).

I have more precisely estimated the consumption of my system: the max output current is less than 500mA, and when the system goes into standby (to preserve the duration of the battery), the current consumption goes down to 1mA; which is the efficiency of MP2313 in such condition?

Do you think another of your part number is more suitable for this kind of application?

Thank you! Kind regards
