nRF52833: ~60 mA current spikes during light sleep on PPK2https://devzone.nordicsemi.com/f/nordic-q-a/127546/nrf52833-60-ma-current-spikes-during-light-sleep-on-ppk2Hi Nordic Team, I’m observing ~60 mA (or higher) current spikes while measuring with Power Profiler Kit II (PPK2) on an nRF52833 . Outside of these spikes the system sits around ~24 &#181;A average (light sleep/idle).

Unfortunately as the PPK2 change measurement range during these short pulses it may show higher current than it actually is.&nbsp;<a href="https://docs.nordicsemi.com/bundle/ug_ppk2/page/UG/ppk/ppk_measure_resolution.html">https://docs.nordicsemi.com/bundle/ug_ppk2/page/UG/ppk/ppk_measure_resolution.html</a>&nbsp;</p> <p>There is no good workaround to this, other than add much more decoupling on VDD to reduce the refresh spikes.</p> <p>Kenneth</p><div style="clear:both;"></div>
