We have custom board with Power block based on LAUNCHXL-CC1352P and application based on simple peripheral,
Our problem is some of boards starts consumpting too much current with a ripple on DCDC output.
We tried use empty project to eliminate software cause and result is same. DCDC enabled by example default.
Chip revision: CC1352P1F3 Rev:E
Ripple on DCDC Output (1-2 different boards, 3 Peaks zoomed in)
Current Consumption(Avarage rises from ~30 uA's to 2-3 mA's), Periodic consumption due problem ~2.5mS Ipeak 19mA
What can be cause some of boards starts to do this behavior after a while?
