It gets complicated to find the right solution since it is very system specific. I would say that it is better to look at reference designs to see how the compensation network is made and what techniques where used to eliminate the overshoot…
Other Parts Discussed in Thread: PMP7932 Hi Sir,.
we refered PMP7932 of LM5000SDX-3, it`s +12V,0.25A output,
could it be change for 24V with 100-200mA output design,
how to make GND between ISO-GND ? Is it like as "SWIFT" inverting buck ?
I believe you have a lot of room to play with. I believe one of the issues is you have a compensation network for a TL431 higher Iq device on your LMV431 which is a low Iq device.
For example, you do not need R108 because that is a biasing…
