https://devzone.nordicsemi.com/f/nordic-q-a/86926/nrf5340-pwm-current-consumptionHi, I encountered that the PWM couldn&#39;t be closed completely, it still has about 100uA after PWM is uninitialized. For troubleshooting purposes, I have posted my code to a simple project and tested it on the nRF5340-DK. Please check the attachmenten-USTelligent Community 13Wed, 20 Apr 2022 10:18:23 GMThttps://devzone.nordicsemi.com/thread/363845?ContentTypeID=1Wed, 20 Apr 2022 10:18:23 GMT137ad170-7792-4731-bb38-c0d22fbe4515:eb1e40f6-68f6-4403-a9ad-10524ea5993eVidar Berg<p>Hi,</p> <p>Sorry for the delayed response. I notice from your code that you are starting the HF crystal oscillator in PWM_Init(), but never stopping it again. Please try to call NRF_CLOCK-&gt;TASKS_HFCLKSTOP = 1; from PWM_Uninit() and see if you get the same result.</p> <p>Best regards,</p> <p>Vidar</p><div style="clear:both;"></div>
