Current consumption on PMIC for i.MX6UL

Hello,

We are drawing peripheral power rails of i.MX6UL from PMIC. We are using SW1A switcher which has capacity of 1A. The peripheral connections are shown below.

I am afraid whether 1A capacity of SW1A is sufficient to drive all the peripheral interfaces or not. Kindly confirm.

 

I have also given provision to drive these rails using SW2 regulator which has current capacity of 1.25A(higher than SW1A). But let me know if I connect SW2 to above power rails, will it disturb the power on/off sequecing of the CPU or not.

Can I share some power rails on SW1A and some on SW2? Will it disturb the power on/off sequecing of the CPU or not?

Regards,

Surendra
