UCC28630: Flyback converter using UCC28630 in Tina Ti

Hi Usman,

Thank you for the query on UCC28630. We currently do not have TINA/SPICE model based on UCC2863x devices.

You can copy this reference design based on PMP9041 which meets your design requirements and based on UCC28710.

https://www.ti.com/tool/PMP9041

The spice model can be downloaded here.

Above is just one example. The same could be implemented with other ICs like UCC28730/40 etc.

Hi Harish!

I have designed the circuit using the referred design. But the output is zero and not good.

Please help me in designing a good circuit that gives me 24V DC output 

FLYBACK DDD.TSC

Hi Usman,

Please use this TINA schematic to modify according to your requirements.

slum539.tsc

Thank you

Dear Harish!

Please don't mind but I have already taken the components including ucc28710 to design according to my need but of no use. 

You can check the above file I sent you. I have used all these components.

I just need 24V with 2A DC output. That's my requirement.

Hi Usman,

The current sense/ Rvs1 and Rvs2 look fine.

I suggest increasing the output capacitance to 600uF.

Second check the transformer turns ratio. 

Consider increasing the Cvdd capacitance. 

Please try to use similar components to PMP9041 which I mentioned above.

Regards,

Harish

Ok I will do so

Is it possible to export the above mentioned Webench design to Tina TI?

I have seen this option on top right corner and have tried many times to export the file to tina TI but nothing happens. Could you please do this for me?

I think you are not taking interest in helping me. 

I told you that these all don't work for me. Kindly before suggesting me anything, please check whether this works or not. 

The above mentioned changes don't work for me.

Change the integration order to 3 in solver options along with changing your transformer turns ratio as suggested before Np=48/Ns=12/Nb=10 turns. The simulations seems to be slow, but it works.

How could I change the order of circuit?

Could you please do this yourself.

I shall be very thankful to you 

Please refer the screenshot below to set the solver options in TINA.
