UC2825: Closest PSpice Model to the UC2825

Hi,

I am trying to run simulation on the UC2825, but cannot find its Pspice model, the closest part model I can find is the UC1846, but LTSpice gives an error  “Too few nodes”.

 Is there anything you can do to help me simulate a full bridge PWM controller PSU with a similar controller to the UC2825.

 Our IT will not allow us to install any unapproved software.  They will not approve Tina-TI or Pspice for TI.

Thanks

Andy
