Hello
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...

It seems that 7841=3784+PMBus
and 3784 SPICE model can be used for 7841 simulation;)
But I would like to have confirmation from ADI engineers...
Hi Victor,
Yes, you are right. The LTspice Model of LTC7841 is not available at present, but the LTpowerCAD model of LTC7841 is available for checking the power stage performance.
And as you mentioned, 7841=3784+PMBus. At VOUT_COMMAND = 50% (1.2V reference), the 3784 and 7841 analog functionality are identical.

Hi John
Yes, you are correct.
I received the same answer from ADI Tech Support.
7841 can be modeled in LTSpice as 3784 with assumption that 7841 will use Vref = 1.2V

Victor
