https://devzone.nordicsemi.com/f/nordic-q-a/18124/dc-dc-current-consumptionGood morning Nordic team, I was measuring the nRF52832 chip in DC/DC mode. Everything went just as expected. Now I was looking at the current consumption when the radio is off and it resulted in just 3 &#181;A. But while I was reading in the DevZone Ien-USTelligent Community 13Fri, 02 Dec 2016 15:40:12 GMThttps://devzone.nordicsemi.com/thread/69921?ContentTypeID=1Fri, 02 Dec 2016 15:40:12 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6287200b-9282-405a-a0c2-0ae6bf600acdbjorn-spockeli<p>Yes, that sounds like a reasonable current consumption value. If you take a look in the nRF52832 Product Specification, Section 17.1.1, under Current Consumption Scenarios you&#39;ll see the following</p> <pre><code>ION_RAMOFF_RTC System ON, No RAM retention, Wake on RTC 1.9 μA </code></pre> <p>Note: The values are typical(i.e.nominal) and deviations due to process variations are to be expected.</p> <p>The nRF52832 will automatically switch between LDO and DC/DC regulator based on load to maximize efficiency. In addition both the LDO and DCDC have two modes of operation. Normal mode and refresh mode. Refresh mode is used when the current consumption is low in order to further maximize the efficiency. Refresh mode works by charging up internal caps regularly to provide power to the chip.</p> <p>Best regards</p> <p>Bjørn</p><div style="clear:both;"></div>
