nPM1100-EK apparent current reverse leak through VBAThttps://devzone.nordicsemi.com/f/nordic-q-a/90954/npm1100-ek-apparent-current-reverse-leak-through-vbatHi All. I am checking battery autonomy with different settings in my Module (with an nRF52840 SoC inside) since, in my project, this is a critical restraint. I am feeding my Module at 3V from an I-Lithium battery connected to the Vbat pin of an nPM1100en-USTelligent Community 13Tue, 16 Aug 2022 09:54:01 GMTRE: nPM1100-EK apparent current reverse leak through VBAThttps://devzone.nordicsemi.com/thread/381727?ContentTypeID=1Tue, 16 Aug 2022 09:54:01 GMT137ad170-7792-4731-bb38-c0d22fbe4515:114236ca-f20b-40ca-84f6-9cc854ef88a9p143<p>You were right Stian. The SW1 default setting was the culprit. Now, Vbat works flawlessly.

AUTO or PWM? In PWM mode the quiescent current is high, while in AUTO it is switching between the most optimal modes in terms of efficiency. Can you please post the schematics and I will try to reproduce your setup and measurements here. Thanks</p> <p>Best regards,<br />Stian</p><div style="clear:both;"></div>
