TPS631010: Beat frequency issue

Part Number: TPS631010

Tool/software:

Hi Team,

Customer are now also trying to use 3 three TPS631010 in parallel with one input rail and three output rail, using independent feedback resistor.

They want to know will this configuration cause the beat frequency problem if they don't want to add input inductor filter due to space limit.

Do we have any material or insight can help customer deal with this issue?

If we don't have the beat frequency issue, what is the reason? Are we have some internal design to solve it?

Thank you
