Hi, Kleinstein,
I have been giving your suggestions consideration. They have good merit. I think it would be a good idea, for you to start a separate thread discussing
- the op amp selection factors
- the MOSFET selection factors
- and, what changes are needed (broadly,) in the circuit, based on these selections.
I know that I would be interested and, certainly, many others.
I looked at the IRFP250. It appears to be a good, reasonably priced candidate. What do you think of the Microchip MTP6002 op amp, as a match, for it? It might be best to answer, in the new thread, to keep from highjacking Jay...
