Hi Bordodynov,
Thank you for your model of MC34074P. We have been using thousands of the MC33074 and MC33072 in our boards.? I designed the old school way of actual breadboarding and pcb proto before launching to final production. I just started LTSpice 3 mos ago as I just came accross it by accident through ready to test simulations of LT smps ic's. We use also a lot of LT and AD devices by the way. I found your MC34074P?(which is same family as MC33074/2/1) then in the LTspice Yahoo files, but I didn't know how to make use of it. Now I was already able to add it to my library and actually start simulating with it.?
Thanks to Andy for patiently tutoring me.?
Appreciate also all the hard work Helmut has been throwing in to make such a hugh volume of achives available to the community especially the newbies.
Best regards,
Eric
