Hello,




I'm trying to setup the LTM4626 circuit in LTSpice based on the Demo Board DC2665A-A. As you can see the PGOOD pin is tied to INTVCC through a 100K resistor.


DC2665A-A Demo Schematic

But when I simulate the above LTSpice circuit my output is not 3.3V.


 




Now if I remove PGOOD from being tied to INTVCC then I get 3.3V.




Please help.
