Tool/software: TINA-TI or Spice Models

Hi,

I tried simulating the PMP7282 (Dual Phase Buck Converter) circuit using TINA software for LM5116. I am not able to get the required output and analyze the simulation. I tried modifying the values but dint get the required output. Request you to provide a solution for the same, if there is any errors in the circuit.

Hi,

Do you know the simulation works with the actual component value from PMP7282?

Thanks

Hi Arief,

Thanks for the reply.

As mentioned earlier, i have tried using the actual values also but i was unable to get the output for both the phases of the buck converter, Please help out in solving the problem.

Regards

Hi Karthik,

Thanks for your reply. I have gone through the FAQs and tried taking some of the mentioned actions but there seems to be no improvement as though. I am sharing my schematic. Please guide us with suitable solutions for the same.

Thanks in advance.

Hi Anushree,

Currently, LM5116 device is not modelled to support 2 phase configuration shown in PMP7282 schematic.

We might need to update the model to support this configuration.

Thanks,

Vivek Agarwal
