Hi folks!
I want to ask a question regarding the current consumption of the TPS63030. I have made some calculations, but wanted to be sure that there is nothing wrong with this.
If the load current at the output of the regulator is 27.4uA, then I guess that the total current consumption of the regulator is
[1] the quiescent current (35uA as stated in the datasheet) and
[2] the current required due to the efficiency of the regulator, which at this load current level is around 60% or less (I am talking about the diagram in Figure 3 / page 7 of the datasheet). thus we need an extra 27.4uA * 60% = 16.44uA
Total current consumption is 16.44uA + 35uA = 51.44uA
Isn't that correct? Do you see any error in this? Is there any other current that I have not taken into consideration?
