LM5122: Programmable current limit in LM5122

Hi Mudit,

I am sorry for this misunderstanding. LM5122 is indeed capable of multi-phase operation. I was referring to the implementation of the external cc controller, which I did not find any reference design for with this device.

We do have several ref designs in multi phase operation. An example would be PMP9309:

You can look for additional designs using LM5122 here:

Dear Niklas,

Thanks for the link  .

 all links have internal error amplifier used for design  and its not doing which i am planning .

since its a customer driven project and small deliverable time i am planning to use UC3843 for temporary basis . i have completed simulation with  external compensation for CV and its working fine .

CC mode is not working as expected . pls have a look and let me know anything i am missing.

Regards

Hi Mudit,

Thanks for the update.
It is good to hear that the external compensation works fine with the UC3843 part.
Unfortunately, I am no expert for this device.

Could you please open a new thread for a review of the UCC3843 schematic and model?
This will be then assigned to the according product line.

If you have any open questions on the LM5122 device, feel free to let me know over here.

Thanks and best regards,
Niklas
