https://devzone.nordicsemi.com/f/nordic-q-a/14455/off-current-in-dc-dc-modeHello Everyone, I am designing the prototype using NRF51822 and i have choosen the DC DC power mode but the real problem is most of the time my radio will be sleeping so i just wanted to know how much current the DC DC mode will consume during sleepen-USTelligent Community 13Mon, 13 Jun 2016 10:47:30 GMThttps://devzone.nordicsemi.com/thread/55213?ContentTypeID=1Mon, 13 Jun 2016 10:47:30 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e9b72c63-889d-49ae-8832-ebb009480bf4&#216;yvind Karlsen<p>The DC/DC in itself consumes 300 µA, this is added to the currents consumed found in the specifications.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/55212?ContentTypeID=1Mon, 13 Jun 2016 09:44:47 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a4cb39d5-4086-44d1-917a-2182104f2636MARTIN FR<p>could you please tell me appoximatley how much does it will consume dc dc mode during sleep ?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/55211?ContentTypeID=1Mon, 13 Jun 2016 09:20:12 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fbd03efe-f4dd-4fe5-8472-557a9a98c8b6&#216;yvind Karlsen<p>Hi,</p> <p>Please refer to <a href="https://devzone.nordicsemi.com/question/18574/nrf51822-power-consumption-when-ble-advertisingconnected/?answer=18589#post-id-18589">this post</a>. DC/DC mode has a higher current draw in sleep modes than the LDO, hence it is only activated when it achieves better performance, i.e. when the radio is transmitting or under heavy CPU load.</p> <p>Best regards,</p> <p>Øyvind</p><div style="clear:both;"></div>
