https://devzone.nordicsemi.com/f/nordic-q-a/102806/power-configuration-npm1300-nrf52832Hello! I am in the schematic design phase of my project and principally I am using the nRF52832 SOC along with the nPM1300 PMIC. The device will of course be powered by a 1S lipo, and the PMIC will handle the charging of this device, and my question relatesen-USTelligent Community 13Mon, 14 Aug 2023 15:51:46 GMThttps://devzone.nordicsemi.com/thread/441223?ContentTypeID=1Mon, 14 Aug 2023 15:51:46 GMT137ad170-7792-4731-bb38-c0d22fbe4515:719c7ce5-3b48-4ddd-9445-49a223e6226eoolaruu<p>Thank you, that is what I presumed but did not have confirmation of.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/441173?ContentTypeID=1Mon, 14 Aug 2023 13:25:05 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ce885679-8cae-4c86-ac0d-df911bac34f8ketiljo<p>You will gain efficiency by using the internal DCDC converter in the nRF52832. The peak current drawn by the radio is much lower when this is used. The nPM1300 can supply the nRF52832 with the wanted supply voltage, 3.3 V for instance. The internal parts of the nRF52832 operates at lower voltages, e.g. 1.7 V for the radio and the DCDC is more efficient as a step down converter than a LDO.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/441058?ContentTypeID=1Sun, 13 Aug 2023 20:53:55 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1a6e33e5-0232-4460-916c-97c77611a24boolaruu<p>Maybe the DCDC converter supplies the internal voltages required by the SoC peripherals or something, and supplying the SoC&#39;s native voltage (3V3?) doesn&#39;t buy you anything?</p><div style="clear:both;"></div>
