ZXGD3103

ZXGD3103N8 SYNCHRONOUS MOSFET CONTROLLER Description Features The ZXGD3103 is intended to drive MOSFETS configured as ideal diode replacements. The device is comprised of a differential amplifier detector stage and high current driver. The detector 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.  5 to15V VCC Range  Operation Up to 250kHz  180V Drain Voltage Rating  Proportional Gate Drive to Minimize Body Diode Conduction  Turn-off Propagation Delay 15ns and Turn-off Time 20ns  Detector Threshold Voltage ~10mV Once the positive voltage is applied to the Gate the MOSFET switches on allowing reverse current flow. The detectors’ output voltage is then proportional to the MOSFET Drain-Source reverse voltage drop and this is applied to the Gate via the driver. This action provides a rapid turn off as current decays.  Standby Current 5mA  Suitable for Discontinuous Mode (DCM), Critical Conduction Mode (CrCM) and Continuous Mode (CCM) Operation  Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)  Halogen and Antimony Free. “Green” Device (Note 3) Applications Flyback Converters in:  Low Voltage AC/DC Adaptors  LED TV, Monitors, Set Top Boxes Mechanical Data  Case: SO-8  Case material: Molded Plastic. ―Green‖ Molding Compound UL Flammability Rating 94V-0  Moisture Sensitivity: Level 1 per J-STD-020 Resonant Converters in:  Higher Power PSU - Telecoms and Server PS...
