https://devzone.nordicsemi.com/f/nordic-q-a/92962/power-supply-efficiency-power-consumption-nrf5340Hello All, I have few questions below: - What is the efficiency of the embedded DC/DC converters in the nRF53 circuit? What is the difference in efficiency when the circuit operates in High-Voltage mode and Normal-Voltage mode? - What is the efficiencyen-USTelligent Community 13Wed, 19 Oct 2022 07:01:17 GMThttps://devzone.nordicsemi.com/thread/391332?ContentTypeID=1Wed, 19 Oct 2022 07:01:17 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5cdb749b-a857-42a0-8fbd-52a276257cfcSimonr<p>Hi again</p> <p>Since the regulators on the nRF53 are automatically switched between different modes based on load, our experience is that providing definite answers to these kinds of questions. I would strongly recommend using the <a href="https://devzone.nordicsemi.com/power/w/opp/2/online-power-profiler-for-bluetooth-le">Online Power Profiler</a> to see how the current consumption of an application changes based on voltage, regulator used, and other parameters. You can see how the radio TX/RX current peaks changes, for example.</p> <p>So, unfortunately we do not have any specific numbers on the efficiency for the nRF5340 for you.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/391232?ContentTypeID=1Tue, 18 Oct 2022 14:22:40 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5b8abdc8-c869-4f17-93dc-f916ebf336b6Simonr<p>Hi</p> <p>I will have to get back to you on this, as I need to ask internally if we have any data like this to share. It might take a few days to track down the correct person and information. Thank you for your patience!</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
