Abstract
A buck-boost power converter and a control circuit for the buck-boost converter. The buck-boost power converter includes a first power switch and a second power switch coupled in series between an input port and a reference ground, and a third power switch and a fourth power switch coupled in series between an output port and the reference ground. The control circuit receives a pulse skipping control signal and a zero-crossing indication signal, and controls the second power switch and/or the third power switch to turn on when the pulse skipping control signal controls the buck-boost power converter to enter into a pulse skipping mode and the zero-crossing indication signal indicates that an output inductor current of the buck-boost power converter crosses zero.
