JW7726B Datasheet | JoulWatt Technology

DESCRIPTION Features JW®7726B is a synchronous rectifier controller, used for the secondary side rectification of isolation topologies, such as Active Clamp Flyback and CCM/QR/DCM Flyback. By driving an external MOSFET, JW7726B is able to significantly improve the efficiency paring with the conventional diode rectifier. - Supports Active Clamp Flyback, DCM, Quasi-Resonant, and CCM Flyback - Support High-side and Low-side Rectification - Output Voltage Directly Supply VCC - Low Quiescent Current - Fast Driver Capability for CCM Operation - SOT23-6 Package When JW7726B senses Vds of MOSFET less than -140m V, it turns on the MOSFET. Once the Vds is greater than -3m V, JW7726B turns off the MOSFET. JW7726B supports multiple operation modes, such as DCM, Cr CM, CCM and Quasi-Resonant. By implementing the Joulwatt proprietary technology, JW7726B is able to handle CCM operation. APPLICATIONS - Active Clamp Flyback and Flyback Converters - Adaptor - LCD and PDP TV JW7726B is available in SOT23-6 package. pany’s Logo is Protected, “JW” and “JOULWATT” are Registered Trademarks of Joul Watt technology Inc.
