ABSTRACT:
A push/pull-type control signal generating circuit outputs two control signals to control directly and drive switching actions of two electronic switches of a push/pull-type circuit architecture. The push/pull-type control signal generating circuit has a first AND-gate logic unit, a second AND-gate logic unit, a circuit protection unit, a function generator, a clock generator, a soft boot unit connected to the clock generator, a sample and hold unit, a first comparator connected to the soft boot unit and the function generator, an OR-gate logic unit connected to the soft boot unit, the first comparator and the first and second AND-gate logic units, a second comparator connected to the sample and hold unit, the function generator and the first and second AND-gate logic units, and a dead time control unit connected to the function generator and the first and second AND-gate logic units.
