Hi,

I am currently building Push-Pull converter 12V to 315V 600W 50kHz. I am trying to use UC3846 controller as it seems like properly designed circuit is very robust. I hope someone can help me finding PSpice model of the UC3846(or UCx846 or UCx856) chip, or even better if someone has similar simulation completed. Thank you very much in advance.
 

Hi

I found the model but i can not get the desired output using that model.
Is there anyone that can help with the design for UC3846.
Please, any help is appreciated.

Regards
