Abstract
An amplifier system may include at least one input source, a flyback converter including a pair of complementary metal oxide silicon field effect transistor (MOSFETs), a controller integrated circuit (IC) having a quasi-resonant (QR) pin and configured to provide a biased drive current to the flyback converter, and a transition component arranged at the controller IC and configured to correct pulse width modulation at the IC to ensure the voltage at a transition pin of the IC is above a predefined threshold during a resonant transition.
