Flyback synchronous rectifier

WebFigure 1 shows the typical application circuit of a Flyback converter with MP6902. The IC senses the drain-source voltage of the rectifier and compares it with internal turn-on threshold (-70mV) and turn-off threshold (-30mV) to determine the on/off timing for the SR (Synchronous Rectification) FET, see figure 2: Turn On Phase (t 1) WebSynchronous rectifiers are used to drive power MOSFETs that replace the rectification diodes in the secondary side of SMPS, thus providing high efficiency especially in low-output-voltage, high-current power supplies. Our portfolio of synchronous rectifiers supports the most common topologies: Flyback Forward LLC resonant
