Hi
I'm building a off the line SMPS with about 200W output power (20V, 10A). I'm thinking of using the tl494 PWM controller. I thought its better to do some simulations in spice. I use the Orcad Capture and Pspice for simulations. The software has a simulation model for this IC but I cannot get it to work correctly. So has any of u guys tried to use this model? Any success... Do u have any ideas?
thanks very much
