TPS61261 is used in Li- system,to boost to 3.3Vout for system use.x
when test the 61261 Iq,below questions accounted:
1、When system works,using 2 multimeter to test the input and output current,while input current is 60mA and the output current is 43mA,
2、Test in static state:when system is powered in,but doesn't send data or Images(if the system works in wireless mode, power consumption is11mA; and the image Acquisition consumes 25mA)
the test result is 32mA input current while 24mA output current.
So, should i think that the chip itself consumes 8mA+? But in Datasheet,it should be 29uA。Or any suggestion about this test?
the circuit is designed according to TI datasheet,as following.
