MP5991 SCREF_OCWREF in parallel configuration

Dear Team,

We are using MP5991 in parallel configuration in our design. Could you please let us know the pin 17 When using multiple ICs in parallel, should the SCREF_OCWREF pins be tied together and routed with individual termination resistor to GND, or should each IC have its own independent SCREF_OCWREF pin and dedicated termination resistor not connected to the parallel IC?"

Also for the VTEMP what is the recommended cap value to be placed? can we place 0.1uF?

Thanks and Regards,

John Wesley

Hi John,

Please use the schematic on the datasheet page 3 as a reference.

We also have a 4-phase EVB for your reference:

For the Vtemp Cap, you can use a 1nF cap.

Please let me know if you have any other questions. Thanks!

Best,

Fox
