I am planning to use 10+ TPS82085 parts to supply multiple separated supply rails on a small form factor PCB. I am concerned with the matching fixed switching frequency of these parts on my small PCB. Without a sync pin present, will the slight variations in the switching frequency/phase cause and EMI issues like beat frequencies?
My application is planning to use the enable pins to power sequence the different rails, but some rails will power on at the same time.
Is there a better solution to avoid potential beat frequencies?
Thank you in advance.
