UCC256301: PSIM Model?

Part Number: UCC256301

Hi Team,

CAn you please check and advise with request below?

"

They created a model for the UCC256301 as there is no PSIM model. As long as there is >1A load on the output, the regulation performance is extremely good. When the output is idle, the regulation performance is bad. We think that this situation will be caused by our model. There is no ready PSIM model on the website for the UCC256301. Do you have too? If so, can you share? When we are sure about the idle regulation, we will start the PCB design.

Thanks in advance

  • Hi Furkan,

    We have only Simplis model for UCC25630x. Ideally when the load is less, controller works in burst mode. There might be an issue with the burst mode implementation in your PSIM model.

    If you are in the initial stage of the project, I would recommend using our latest generation LLC controller UCC25640x which is pin to pin compatible with ucc25630x.
