https://devzone.nordicsemi.com/f/nordic-q-a/22837/enabling-dc-dc-converter-nrf51822Hi Nordic, I am trying to enable the DC/DC converter on a QFAAH10 (revision 3) . I am using the s130 v2.0.1 SD . ---------- 1. sd_power_dcdc_mode_set(NRF_POWER_DCDC_ENABLE); I write &quot;sd_power_dcdc_mode_set(NRF_POWER_DCDC_ENABLE);&quot; in my codeen-USTelligent Community 13Mon, 19 Jun 2017 09:01:58 GMThttps://devzone.nordicsemi.com/thread/89790?ContentTypeID=1Mon, 19 Jun 2017 09:01:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:afb07532-2b5d-4b26-9952-022be8881f2fMindu<p>Thank you for your fast response!! It is a custom board and the external components required are mounted. The problem was that both the output the pin DCC and the input of the radio supply AVDD where attached to the general supply VDD, not between them exclusivily. Silly hardware error!! Thank you.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/89789?ContentTypeID=1Thu, 15 Jun 2017 18:48:53 GMT137ad170-7792-4731-bb38-c0d22fbe4515:560f55fd-e46e-4dbe-9172-e3cc34e277e5J&#248;rgen Holmefjord<p>Are you trying this on a custom board or a development kit from Nordic Semiconductor? If it&#39;s a custom board, do you have the external components required for DCDC on your board? See chapter <a href="http://infocenter.nordicsemi.com/pdf/nRF51822_PS_v3.3.pdf#page=86">11.3.3 of the nRF51822 Product Specifications</a>, and <a href="https://devzone.nordicsemi.com/question/87979/nrf_power-dcdcen-does-not-reduce-power/">this thread</a> for more details.</p><div style="clear:both;"></div>
