Hello,
Does TI have light load efficiency data for this part? I see that it has a light load PFM mode. Customer is interested in the <1mA range.
Thanks,
Michael

HI Micheal,
I can provide some data just for reference.

Hi Nini,
Thank you! Do you also have any data for 3Vin? We're seeing ~50% effiiciency there at 400uA.
Thanks,
Michael
