Flyback synchronous rectifier

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 WebSynchronous Rectifier Controller The NCP43080 is a synchronous rectifier controller for switch mode power supplies. The controller enables high efficiency designs for flyback and quasi resonant flyback topologies. Externally adjustable minimum off−time and on−time blanking periods provides flexibility to drive various MOSFET package types
