Hi , Kaja :

I have try with DTM from SDK v16.0.0, SDK v15.3.0, SDK v14.2.0 ,SDK13.1.0, but  the problem still exsit.

As the following screen shot, In single channel mode, The current cosumption is normal or not ?

I am using following schematic, is there something wrong ?

I have saw  PCA10040 Demo schematic, is it working in DC/DC mode when running DTM? If running DTM in LDO mode , how to change code?
