CC1310: Recharge Pulses getting larger

Part Number: CC1310


Tool/software:


Hi there,
I have been trying to measure the power consumption of the CC1310 on my custom board and I see that the recharge peak pulses are getting larger every time (see attached image). Is this normal?
Does it perhaps have something to do with the fact that as the interval between charges gets longer, the pulse is also higher because the internal Capacitor is being discharged more. 

Regards,
RLB

    Hi,

    But these pulses will not be increasing continuously since they will stabilize at a certain level after a period of time.

    Just as long as the DCDC inductor is 6.8 uH and has a low resistance and the main capacitance is 22 uF; the DCDC should work as expected.
