Dear,
for MPM3695-25, I want to know about the current sharing. for DS, it shows Io have 10% accuracy, for current sharing example in DS shows as below.

So, I want to know, if I got 4pcs MPM3695 paralleling, how many total continues current can provide, is 72A？ how to caculate the total parallel outout current ? thanks.

Hello,

You can parallel up to 6pcs, but it is recommended to parallel 2pcs at most.
I would instead recommend using the MPM3695-100 instead since it would be able to provide up to 100A continuous if the output is up to 1.8V. Please to the Output Voltage Derating on the data sheet.

I hope this helps.

Thanks,
Eliza

the output voltage is 3V, so MPM3695-100 is not suitable. my question is, if I parallel 4pcs MPM3695-25, how big the contuniues output current can reach? 80A or other value, and how to estimate this value?

Hello,
The continuous current would be a maximum of 80A of continuous current assuming proper operating conditions.

Thanks,
Eliza

Sure? is there any testing data to support this? and the proper operating means what?
