https://devzone.nordicsemi.com/f/nordic-q-a/114071/nrf52840-reg0-dcdc-iq-andI&#39;m looking for the quiescent current and efficiency of REG0 DCDC under the conditions of 3.0v ≤ VDDH ≤ 4.2v, VDD=1.8v. This is to determine if external regulation using the TI TPS62840 would yield lower power consumption.

Please note that usually PMIC SOC can achieve better performance compared to built-in buck converter module with the trade-offs such as size and cost.</p> <p>For nRF52840 REG0 DCDC converter, typical quiescent current is around 35uA when it is idle, and around 300uA in normal mode.</p> <p>Typical power efficiency is around 83% when Vin = 3.7V, Vout = 1.8V, at 15mA load current.</p> <p>Typical power efficiency is around 81% when Vin = 4.0V, Vout = 1.8V, at 2mA load current.”</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/499242?ContentTypeID=1Wed, 21 Aug 2024 14:46:59 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8e476172-9d73-483b-8921-5c051f22ca18Kazi Afroza Sultana<p>Hello,</p> <p>I have asked my team about this information.
