  • Description

    JW®7717 is a synchronous rectifier, used for the secondary side rectification of Flyback. By driving an internal MOSFET, JW7717 is able to significantly improve the efficiency comparing with the conventional Diode rectifier.

    When JW7717 senses VDSof internal MOSFET less than -300mV, it turns on the internal MOSFET. Once the VSWis greater than -10mV, JW7717 turns off the internal MOSFET.

    JW7717 supports multiple operation modes, such as DCM, CrCM, CCM and Quasi-Resonant. By implementing the Joulwatt proprietary technology, JW7717 is able to handle CCM operation.

    JW7717 is available in SOP-8 package.
