Multiple LTM4670/LTM4658

Hi Ning,

Yes, you can connect multiple LTM4670s or LTM4658 modules in parallel.

You may also use the respective datasheets as reference for the application.

Hi,

Do you mean that the following connections is possible?

Thank you.

Hi Rufino,

on the website, it indicates the max parallel output current is only 40 A.

Hi Ning,

Connecting five LTM4670 channels in parallel to produce 50A is possible, but the stability of the converter at this configuration is not guaranteed. Could you give more details of your application for this part? It would help us in recommending a more suitable part for your application. Thanks!

Hi Rufino,

i'm looking for at least 50A output current with low EMI emission.

Hi Ning,

LTM4680 is a good alternative if you need 50A output current, or you could use LTM4700 if you need two 50A channels. In general, µModules have good EMI performance due to the Silent Switcher topology used in designing them. You may also use the LTPowerCAD tool to simulate the EMI performance of your application.
