TPS61099: Quiescent current
Part Number: TPS61099
Customer want to measure TPS61099 quiescent current into VOUT pin. We set up the test bench using TPS61099-768 EVM. Remove feedback resistor, R1, R2, connect a 2V voltage to FB pin through 5kohm resistor. Connect a 5V voltage to the VOUT pin and EN pin, leave the VIN open. And then check the power supply current to VOUT pin, it shows for about 0.9uA, much smaller than the datasheet. Could you give some comments if this is the right method to measure the quiescent to VOUT pin?
please power the VIN to 3.7V. the typical IQ in the datasheet is 0.6uA, actually closed to customer's data.

After connect the input voltage to 2V, and then add a 5V voltage to Vout, get the similar to datasheet.
