JW77198B Overview
JW®77198B is a synchronous rectifier, used for the secondary side rectification of flyback. By driving an internal MOSFET, JW77198B is able to significantly improve the efficiency paring with the conventional Diode rectifier. When JW77198B senses VDS of internal MOSFET less than -300mV, it turns on the internal MOSFET.
