I have a question regarding multi-phase operation: On the MPQ8645P and MP8796B datasheets It is unclear how design the feedback network. In particular on MPQ8645P DS page2 the two devices are usign their own internal feedback but on page 17 two of them are using an external feedback each and the last one is using the interal one. On MP8796B DS page18 All devices are usint the internal one, BUT, the evaluation board EVREF0105A, where 6 MP8796B are present in an “up-to” 6 phase operation configuration, all of them are sharing the same feedback network. This configuration is unclear.
I am looking for more information about how design the feedback network in a MULTI-PHASE OPERATION, since datasheets don’t provide enough information.
How can those devices have different feedback networks (internal or external)? since all of them are subject to different tolerances?
Thanks in advance
