https://devzone.nordicsemi.com/f/nordic-q-a/50468/disappointing-dcdc-current-improvementI am trying to get the DCDC running on my custom NRF51822 board. It is running but the results are a bit disappointing. If I do a test and enable the TX with and without the DCDC enable I only see a difference of a little bit more then 1mA.

If the battery is not able to deliver the current needed for the peak currents the voltage will drop, and the DCDC efficiency is proportional to the input voltage.</p><div style="clear:both;"></div>
