TMS320F280037: Full Bridge LLC solution using C2000 devices.

Part Number: TMS320F280037
Other Parts Discussed in Thread: TMS320F28335, TIDM-1001

Hi,

I'm looking for the full bridge LLC with the C2000.

My customer is developing a full bridge LLC with a TMS320F28335 on the test board.

Now he is considering new devices for cost reduction and manufacturing.

Can the F28039 implement FB-LLC?

He FB-LLC switching frequency he will be using is 300 KHz.

And he doesn't use the CLA.

How is CPU burden calculated?

How do I know if a device is appropriate for power topology?

Please recommend a device suitable for FB-LLC.

    Hi SY,

    For now, f28002x(single core) should be able to support already. f28003x can also do it but since he does not need the CLA, it maybe a little bit over-killed. We have some reference design that supports LLC topology such as TIDM-1001 which we have the data of CPU burden. 

    Regards,

    Chen
