Part Number: DRA744
Other Parts Discussed in Thread: DSLR,

Tool/software:

We need some clarifications regarding DSLR IC (APN: 28155429) used in M&M IVI project.
Currently we are configuring both switching regulators to 3V3 and 5V outputs. We observed following transients on the 3V3 supply rails during board bootup. Could you please help to understand possible reasons for below and how to avoid it.

    With the E2E title/part number DRA744, this question is routed to the Processors group.  Can you provide more information on DSLR IC (part number)?  I assume its a power regulator IC and possibly this question is for that team.
