JW77198B Datasheet (JoulWatt) - 80V Synchronous Rectifier

JW77198B, 80V Synchronous Rectifier

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 comparing with the conventional Diode rectifier.

When JW77198B senses VDS of internal MOSFET less than -300mV, it turns
