Data sheet Fig18 of UCC28070 that it connect an IMO pin directly and do not malfunction?
Is not resistance necessary to separate when IMO pin connect?
This is a case where the two UCC28070s are connected in parallel. The use of a single RIMO resistor to ground provides a common reference for all four phases of the circuit. since they are current sources the currents from the two UCC28070 will automatically add aand don't need any resistors between them.

Dear John Bottrill
Thank you very much for your answer.May I ask one more question?
I use UCC28070 and operate it in Four-Phase period, but switching becomes unstable.
Would you show me a figure of controller part PCB Layout if you are possible?
Is there Four-Phase period such as PCB Layout of slur037.pdf?
I hope your kind answer.

I don't have anything like that.
Thank you very much for thinking of answer.
