Tool/software:
I inherited this design. Originally we had set up REGIN as shown in the data sheet. When our board was moved to a bigger stack (32Ah from 19.2 Ah). We started seeing spikes on REGIN and blowing parts next to this pin. I am putting in a LDO for powering REGIN, but with the larger stack will that fix my problem or do I need to re-design the whole system?
Thanks.
