LMZ31710 Current sharing

Other Parts Discussed in Thread: LMZ31710

Hi, 

I am using LMZ31710 in current sharing mode. Is this module recommended to use with current sharing and split voltage options?

If i can use, is it compulsory to give external SYNC clock? I can not provide this externally, shall i give Rrt for first module and connect SYNC output to RT/CLK of second pin?

and is it required to connect Rrt resistor for second module also?

please clarify these doubts..

Thanks in advance,

Mahesh.gv

    Hi Mahesh,

    Yes, it is OK to current share in split voltage applications.

    Yes, set the switching frequency using Rrt on the first module and drive the RT/CLK pin of the second using the SYNC_OUT of the first. I would place the correct Rrt resistor on the second module as well.

    You can contact me directly at jarrigo@ti.com.
