Help Simulating Application Circuit #5 of LTC3350 Datasheet using LTspice

[joe306]

Hello, I am trying to simulate a circuit found on page 41 of the datasheet for the LTC3350. I am using LTSpice and when I run the Simulation get the message "Pseudo-Transcient Analysis that runs forever until I hit the ESC button. That's my first problem the second is that I'm not getting the correct Vout voltage. I have all my parameters set like the datasheet.

I'll upload the datasheet and LTSpice design.

Thank you,
Joe

Hi.

Check these two boxes:



And it will add startup and uic to the simulation command.

Everything will work nicely.
