Hello Helmut,
Indeed, I'll try FAE - thanks for an obvious solution.
Regards,
Olek A

Hello Olek,
I remember that I tried and the simulation took too long for
my free time. Please be aware that practically no user of this
group is an employee of LTC.
Why not asking your nearly located FAE (Filed Application Engineer)
from LTC? They may be able to help.
Best regards,
Helmut
PS: I am also not an employee of LTC.

Really nobody is able to help me ?
I need a solution to get an isolated dc/dc converter with Vin = +8...30V and Vout = +3.2...4.3V at Iout=20 A.
The LTC3765 & 66 chips seems to be a nice solution, but at lower Vin this combo doesn't simulate peoperly/
Thanks in advance, OlekA

Hello!
I tried to simulate a +9...+30 Vin, +3.5...+4.2 Vout dc/dc converter using LTC3765 & 66 chips.
While it simulates nice using default LT settings as in jigs directory,
any attempt to use lower input voltage in the area +9..12 Vin failed due to abnormal Ndrv pin behaviour.
After several milliseconds of proper work it simply stops feeding Vcc pin through mosfet.
Why it makes this "brownout" ?
