Hi all

I am running Orcad 16.0.
I am trying to build and simulate a flyback converter whit the UC2844/1844 PWM-controller. But I'm keep getting a green circle in the top left corner of the controller, and when I double-click on the circle I get the following message:

WARNING: [NET0093]
No PSpiceTemplate for U5, ignoring​
How can I overcome this error

Many thanks

MrJimbeam

Try placing symbol from ...\tools\capture\library\pspice\advanls\CONTROLLER.OLB. It may be using the symbol from tools\capture\library\regulator.olb or tools\capture\library\Misc2.olb. These libraries do not have simulation model associated with them and you will get above error.
In case you are using the symbols from ...\tools\capture\library\pspice\advanls\CONTROLLER.OLB, please check the PSpice setup. You should have nom.lib configured as GLOBAL lib and you should have ..\tools\PSpice\Library folder in Library path, under Simulation Setting, Configuration File, Library TAB.

Hope this helps.

Hi,

please could you tell me where did you find the .lib file of the uc2844? I have found an .olb file in the website of Texas Instruments.
I need this library in order to use it in a PSPICE simulation.

thanks a lot!!!

I have already searched for it in TI website but there is not a .lib file dedicated to the UC2844. Instead of the .lib file of UC2844 I have found the .lib file of the UCC28C41, -2 and -3 "http://www.ti.com/adc/docs/midlevel.tsp?contentId=55102" . I will try to simulate this follower IC and I hope I will understand its function.
