LMZ31520: Quiescent current during operation

I was wondering what the power supply quiescent current is during active operation, I could not find that information in the datasheet.

    Hi Josh,

    I took a LMZ31520EVM with 12Vin/3.3Vout at 25degC room temperature and measured the standby current at no load. In FCCM mode the standby current was roughly 110mA while in Auto-Skip Eco Mode the current was 2mA for this condition. 

    Regards,
