We are investigating why the power-on current is high (1.2mA) on the failed board (using NRF52840). We found that the DCC pin behaves differently. The DCC pin is continuously switching on the unit with the high power-on current. Where is the NRF failing? The design is following the reference and connected LC (10uH , 15nH inductor, 1uF and 47nf cap)
