https://devzone.nordicsemi.com/f/nordic-q-a/124330/how-to-disable-dc-dc-converter-on-nrf54l-deviceHi all, I’m working with an nRF-based board and need to via software disable the internal DC-DC converter and use the LDO exclusively for testing purposes. I’m unclear on: How to do this? When I can do this action for it to properly take effecten-USTelligent Community 13Fri, 12 Sep 2025 11:41:51 GMThttps://devzone.nordicsemi.com/thread/548592?ContentTypeID=1Fri, 12 Sep 2025 11:41:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0c2b867a-f9e4-4d9e-8fd1-0e9146dd4b8dAHaug<p>Hi,</p> <p>The nRF54L15 only supports DC/DC. From the&nbsp;<a href="https://docs.nordicsemi.com/bundle/ps_nrf54L15/page/keyfeatures_html5.html">54l15 datasheet chapter 5.7.1:</a></p> <p><em>&quot;5.7.1 VREGMAIN — Main regulator VREGMAIN is the main regulator of the system. The device can only be operated in DC/DC mode, ....&quot;,&nbsp;</em>i.e any workaround you do to only use the internal LDO, will result in limitations both w.r.t peak limit current and power consumption in general.&nbsp;</p> <p>What type of device are you aiming for here? On the grid devices/devices that don&#39;t care about current consumption&nbsp;<em>may</em> be an option for the non-supported LDO, but I can&#39;t state that it will work since the device is not characterized for LDO only.</p> <p>Kind regards,<br />Andreas</p><div style="clear:both;"></div>
