Web3 aug. 2006 · The transition from diodes to synchronous-rectification (SR) MOSFETs in secondary circuits of flyback converters increases with each new generation of MOSFETs, improving performance at little or ... WebFlyback converter operation can be divided into two modes, depending on the minimum value of the inductor current in each cycle. If the MOSFET switches from tOFF to tON before the inductor is completely discharged, then the current in the inductor is never zero. This operation is called continuous conduction mode (CCM).
Websecondary turns giving an Np2s of 1.2. After selecting the turn’s ratio it should be verified the 40-Vinternal MOSFET of the TPS55340 is sufficient for the voltage stress in the design. In a flyback topology the drain-to-sourcevoltage across the low-sideMOSFET is the input voltage plus the output voltage reflected to the transformer primary.
