Eric,
Thank you very much for the pointer.
Yes I previously did connect the sense signal to the wrong input. In the most recent schematic above the sense signal is attached to the +input rather than the -input like in your sim.
I changed that and added a couple other changes. All came from suggestions like yours.
I see that your circuit is not as changed as my most recent one. Is that a mild suggestion from you?
BTW, what software are your using? It seems most capable.
Thank you,
Moniker
