That's how I generated my SMPS models. I have used LTSpice before, with great success for LT products and simple circuits. I spent some time playing with Terry's circuit and Jims comments with no success. I also played around with genome's ckt but decided for a simple person like me that it would be easier to breadboard it. So, i did the design in protel, and I started laying out the PCB, then I got bored and found a bottle of wine, a kabana and the internet....... Sigh, i spend all day in front of computers writing things like strncpy(&hello,"world"sizeof(&hello)); and not designing circuits, so i get bored real easy. I then get remotivated for an hour or so every 2-3 days and connect a few more nets in protel. This project is for my dad who is a retired mechanical engineer, hopefully i can deliver before he passes on. > >Kevin Aylward 431infoEXTRACT(a)anasoft.co.uk >http://www.anasoft.co.uk >SuperSpice, a very affordable Mixed-Mode >Windows Simulator with Schematic Capture, >Waveform Display, FFT's and Filter Design. > >"There are none more ignorant and useless,than they that seek answers >on their knees, with their eyes closed" >
