Dear Sir/Madam,

Hello,

We have a project with I.MX6 dual/quad core processor which we use PF0100 F0 as PMIC. For USB I have another 5 volts supply already and therefore I don't want to populate SWBST components in PCB. Does it cause stability problems to PF0100 F0?

Thanks and best regards.

Hi Mehmet Ali,

You should check out the following document:

http://cache.freescale.com/files/analog/doc/app_note/AN4717.pdf

For every pin, there is a column for "Recommended connection when not used".

For your specific question, it says in the document:

44 - SWBSTFB --> Leave floating

45 - SWBSTIN --> Connect to VIN

46 - SWBSTLX --> Leave floating

Best regards,

Durmuş
