R Clark,
As Udo wrote, LTspice has examples in .ASC for those parts, and for almost every part made by Linear Technology and Analog Devices.? You already have those example schematics on your computer's drive.? An easy way to find those example circuits is this:? Starting with your schematic that has one of those parts, right-click on the LTC1922-1 or LTC3722 symbol that is on your schematic, and choose "Open this macromodel's test fixture."? Now you have that example schematic open in LTspice, and you can run it and plot the results.?
When you wrote, "Phase shift is not working? / I must miss something,"? what was the phase shift?? If something is not working in your simulation, please consider uploading YOUR schematic to the group's "Temp" folder, as John recommends.? It should be the actual schematic .ASC file (NOT a picture of it), and it should include all symbols (.ASY files) and their models for anything that did not come with LTspice, but nothing else.
