Part Number: TPS630250

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.
