WebTransition Mode always keeps the converter in Critical Conduction Mode (CrCM) by varying the switching frequency. Boundary Mode sets the middle point between the two input … WebCharacteristics. The flyback converter is an isolated version of the buck-boost converter. Depending on the winding ratio of the coupled power inductor, the input voltage can be higher, lower or equal to the output voltage. The isolated output feedback can be acquired either directly from a winding of the transformer or by using an optocoupler.
