ZXGD3107N8TC

ZXGD3107N8 SYNCHRONOUS MOSFET CONTROLLER IN SO-8 Description Features ZXGD3107N8 synchronous controller is designed for driving a MOSFET as an ideal rectifier. This is to replace a diode for increasing the power transfer efficiency.     Proportional Gate Drive to Minimize Body Diode Conduction Low Standby Power with Quiescent Supply Current < 1mA 4.5V Operation Enables Low Voltage Supply 40V VCC Rating Proportional Gate drive control monitors the reverse voltage of the MOSFET such that if body diode conduction occurs, a positive voltage is applied to the MOSFET’s GATE pin. Once the positive voltage is applied to the Gate, the MOSFET switches on allowing reverse current flow. The controllers’ output voltage is then proportional to the MOSFET drain-source voltage and this is applied to the Gate via the driver. This action minimizes body diode conduction while enabling a rapid MOSFET turn-off as drain current decays to zero.       200V Drain Voltage Rating Operation up to 500kHz Critical Conduction Mode (CrCM) & Continuous Mode (CCM) Compliant with Eco-Design Directive Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony free. “Green” Device (Note 3) Applications Mechanical Data     Flyback Converters in:  AC-DC Adaptors  Set-Top Boxes  PoE Power Devices   Resonant Converters in:  Telecoms PSU  Laptop Adaptors  Computing Power Supplies – ATX and Server PSU  Case: SO-8 Case Material: Molded Plastic. ―Green‖ Molding Compound.
