LM70880-Q1: Synchronizing two LM70880-Q1, generating two different voltages, so the they are either in-phase or out of phase, with one device as master in DRSS mode.

Tool/software:

I am looking for an application note that shows how to:

Synchronizing two LM70880-Q1, generating two different voltages, for in-phase operation or for out of phase operation, with one device as master in DRSS mode and other device in slave mode.  Is this possible?

If one device is downstream from the other, we are thinking of making them in-phase; if the are creating two different output voltages using the same input voltage we are thinking of making them out of phase.
