ZXGD3103N8

A Product Line of Diodes Incorporated www.DataSheet4U.com ZXGD3103N8 SYNCHRONOUS MOSFET CONTROLLER Description 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. Features Applications Proportional Gate Drive 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 5-15V VCC range Flyback Converters in: Adaptors LCD Monitors Server PSU’s Set Top Boxes LCD TV Resonant Converters LED TV High power Adaptors Street Lighting ATX psu Pin out details Typical Configuration N/C 1 REF 2 8 DRAIN 7 BIAS 6 GND 5 VCC GATEL 3 GATEH 4 SO-8 Ordering information Device Status Package SO8 Part Mark ZXGD3103 Reel size (inches) 13 Tape width (mm) 12 Quantity per reel 2500 ZXGD3103N8TC Production ZXGD3103N8 Document n...
