Hi Team
We've been using R9A06G032NGBG#AC1 as MPU for one of our custom designs. Also, we have referred the EVK (in which BLM15BD102SN1 is used), and in custom design we have added FB1 (BLM15PX601SN1D, please refer the custom design's block diagram attached).
Also, as mentioned in the block diagram, in the power rails we've used Ferrite bead chip (FB_A and FB_B) which causes more ripple for both 1V5 and 1V15 lanes.
Is it recommended to use Ferrite bead in place of FB_A and FB_B?
if yes, can you suggest a part number with the maximum current consumption of 1.6A for 1.15V power rail and 300mA for 1.5V power rail. Please share the technical justification for the same.

Hi sreehari,
Your issue is not RZ/N1D related. It is general question for circuit design. It is better to post your question on Power products forum.
Kind regards.
