i am looking for recommendations for a good pwm controller that could be used for push-pull or bridge converter. So far I found voltage-mode SG3525, and current mode UC3846 (1846 or 2846 are the same thing).

I would like to use current mode, but cannot find any working model of the 3846 for ltpsice. (found some very old pspice model of SG1846, but it would be PITA to convert it)

Do you have any suggestions for a controller that is not obsolete and has a model that would work in LTspice?

p.s. I am trying to stay out of phase-shift for now, as it is my first high power converter and would like to keep it within what I know and undestand.
