UCD9240 is the most suitable for controlling 3 Synchronus Buck Converters.
UCD3138 and C2000 can do the same thing, but they do not usually come with a fully developed firmware.

For working with UCD3138 you will need to write your own firmware. Same probably with C2000.
But UCD9240 is fully tested and GUI configurable.

C2000 is a DSP, closing the loop through it's DSP core. UCD3138 has 3 autonomus loops that once configured can run without any help by the core/firmware.

Hope this helps,

Thanks Yitzhak, for your valuable information

Can you please provide little bit glimpse of how to start with UCD9240?

I want to develop fully functional 3 synchronous buck converters with closed loop control using UCD9240.

What are the primary requirements to start with UCD9240?

Thanks and regards

I will ask Zhiyuan Hu to support you on this. He knows the non-isolated portfolio better than I do.
