Design a multpile output dc-dc power supply with CAN bus in automotive HIL

hello all,

Currently working on a project with 2 SMPS ICs (one buck pos ouput and other buck with neg output)

Vin range from 12V - 42V
Iout upto 15A.

The first IC LM25117-Q1 from Texas Instruments , to set the output voltage I have selected a 12 PIN MCP42010, digital potentiometer. And the data lines to control this Digi POT is done by the dsPIC30F4011 which has a CAN communication.

I am not sure if I understand it right to connect the feedback output pins from the SMPS ICs to either PW0, PW1 or any other pins. I have also attahced a .sch file where i created a LM25117-Q1 symbol with specs..

And the complete block diagram is also attached.

Suggestions, changes, questions are welcomed !

Thanks
