Hello,everybody!
I indende to use LM4651 controller in this configuration and to not use LM4652. I'll replace LM4652 with power mosfet ( for example IRF640 ).
For this change must eliminate the protection ( pin 12 of LM4651 ) and recalculate the feedback. Power supply for LM4651 is +/- 20V and for IRF640 is +/- 60V . Have you an idea what value has Rfl3 rezistor in the feedback and R value in gate of power mosfet.
Any suggest is good for me!
P.S. Scuze my english!
