Hi,
I use TPS610985 and TLV3491 in my project,found that the power consumption is abnormal.Here is the schematic.
(1)The total power of DC/DC is about 5-8uA when R135 is 300Ω. When adjust R135 to 1M, the power consumption is 1.4uA.
(2)If i use software to shutdown the TLV3491,the total power of systerm decrease 2.3uA.
In datasheet of TPS610985 ,it says the consumption is 300nA.Is there any points should I pay attention?The power consumption seems abnormal.Any suggestion?
