Parameters Subject to Change Without Notice
JW7715 is a synchronous rectifier controller, used
for the secondary side rectification of isolation
topologies, such as Flyback, Forward, Half Bridge,
Full Bridge and LLC converter. By driving an
external MOSFET, JW7715 is able to significantly
improve the efficiency comparing with the
conventional Diode rectifier.
When JW7715 senses Vds of MOSFET less than
-300mV, it turns on the MOSFET. Once the Vds is
greater than -10mV, JW7715 turns off the
JW7715 supports multiple operation modes, such
as DCM, CrCM, CCM and Quasi-Resonant. By
implementing the Joulwatt proprietary technology,
JW7715 is able to handle CCM operation.
JW7715 is available in SOT23-6 package..
