The datasheet Quiescent current TYP 35uA, But Test the EVM real Quiescent current around ~65uA,
Please explain test conditions not switching is mean?
I see a PFM mode in EVM no load condition.

Hi James,
Iq is a used for comparing devices. It is defined as the no-load, non-switching input current. Non-switching means that no power switch is on (closed). It is basically a measure on how efficient the internal circuits are, which gives an overall estimation of the light load efficiency.
