ZXGD3103N8TC

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. 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. 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 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)   Mechanical Data Applications   Flyback Converters in:  Low Voltage AC/DC Adaptors  LED TV, Monitors, Set Top Boxes Case: SO-8 Case material: Molded Plastic. ―Green‖ Molding Compound UL Flammability Rating 94V-0 Moisture Sensitivity: Level 1 per J-STD-020 Terminals: Finish - Matte Tin Plated Leads, Solderable per MIL-STD-202, Method 208 Weight: 0.074 grams (Approximate)   Resonant Converters in:  Higher Power PSU - Telecoms and Server PSU  Computing Power Supplies – ATX and Server PSU  Street Lighting  Typical configuration SO-8 DNC DRAIN REF BIAS GATEL GND GATEH VCC Transformer RBIAS RREF REF DRAIN BIAS Vcc ZXGD 3103 C1 GATEL GATEH GND Top View Pin Name GND VCC GATEL GATEH BIAS DRAIN REF DNC Pin Function Ground Power Supply Gate Turn off Gate Turn on Bias connection Drain Sense Reference Do not connect Top View Pin-Out Synchronous Rectifier MOSFET Ordering Information (Note 4) Product ZXGD3103N8TC Notes: Marking ZXGD3103 Reel Size (inches) 13 Tape Width (mm) 12 Quantity per Reel 2,500 1.
