There are some intrinsic drawbacks in traditional push-pull converter, such as higher voltage stress and hard-switching of the switches, so the application area of the converter is limited.
When designing output stage, in order to enhance the efficiency, it uses the push-pull common source stage amplifier as the output stage, the output voltage swing basically reached rail-to-rail.
