What about LTspice support for LTC7841?
I can`t find any models in LTspice installation and LTC7841 product page.Export from LTpowerCAD II to LTspice not work also...
Datasheets for LTC3784 (p.23) and (at least) LTC7841 (p. 31) have note
" The value of the boost capacitor CB needs to be 100 times that of the total input capacitance of the topside MOSFET(s)."
But on all application schematic`s 0…
LTC7841 is a good candidate for your application. It has PMBus interface. Another boost controller with PMBus is LTC7880.
Meanwhile, we have several analog boost controllers like LTC3784.
