Suheyl,
All double-ended topologies (half-bridge, full-bridge, push-pull) simulated in Power Stage Designer will behave the same as you are seeing with the push-pull. The effective frequency of the output inductor is 2x the selected switching frequency. This is not a limitation of the topology and has nothing to do with the controller.

Suheyl,
I do not know what assumptions were made when within the development of TI Power Stage Designer which led to the minimum current being limited to 50% of the max. If the output load current is 12A and each leg is carrying 50%, for some reason the simulator only seems to show the current for one leg as 50% to max. You can change the max current to be the minimum you are wanting to see the waveforms for. I tried this as below.
