TLV62130: Current consumption at no load

Ryo Akashi
Genius 9470 points
Part Number: TLV62130
Hello experts,
I got question for current consumption at no load from customer.
With TLV62130EVM-505, customer set 12Vin and 5Vout.
At no load, input side current is above 10mA. It looks not only Iq.
Do you have any idea for the phenomenon? 
Also, I heard, TPS562210 (D-CAP2 Control) at no load, input side current is almost Iq.
Is there any possibility that DCS-Control cause this phenomenon?
Customer wants to implement very low power consumption at no load.
Thanks and best regards,
Ryo Akashi

    Akashi-san,

    When the TLV62130 is switching, the input current will be more than Iq.  10mA seems to high though.  Looking at Figure 8, the efficiency for 5 V out, 12 V in and .0001 A is about 50%.  That corresponds to 83 uA input current.  Your customer must be making a measurement error.  It takes some additional care to measure it accurately.  Please see this app note:
