X-KW45-EVK power measurement

MSM1 — Mon, 18 Mar 2024 09:34:53 GMT

Hello,

I am measuring power consumption on X-KW45-EVK following the same recommendation as AN13230 application note section "5.2 Measuring current consumption" trying to measure ireg.

I have followed the same recommendation except that i am using only a source meter:

vdd on JP5-3 at 3.3v

gnd on TP18

usb connected on j14

jp10 on buck

the consumption seems strange to me like a noise , i have attached a figure.

Note : i am using lowpower_peripheral application. the application is running fine , i observe advertising packets.

am i missing something ?

Kind Regards,

MSM.
