Part Number: TPS61070

My customer evaluated the quiescent current of TPS61070.

When they raised VBAT from 1.2V, IQ had kept on raising until VBAT=3V and dropped by degrees after that.

The condition and result are the following.

Are these results correct?

Condition

Vout：Open(Vout=5V)

Iout：No Load

Result

VBAT=5V IQ=30uA

VBAT=3V IQ=67uA

VBAT=1.2V IQ=18UA

Best regards,

what is the feedback resistor?
what customer measuring is not IQ, but no load input current
i thinks the current at 1.2V is not correct. are you sure the device still working at VBAT=1.2V?
