ZXGD3101N8TC Diodes Incorporated

A Product Line of Diodes Incorporated ZXGD3101N8 SYNCHRONOUS RECTIFIER CONTROLLER Description Features The ZXGD3101 is intended to drive MOSFETS configured as ideal Turn-off propagation delay 15ns and turn-off time 20ns. diode replacements. The device is comprised of a differential amplifier Suitable for Discontinuous Mode (DCM), Critical detector stage and high current driver. The detector monitors the Conduction Mode (CrCM) and Continuous Mode (CCM) reverse voltage of the MOSFET such that if body diode conduction operation occurs a positive voltage is applied to the MOSFETs Gate pin. Compliant with Energy Star V2.0 and European Code of Conduct V3 Once the positive voltage is applied to the Gate the MOSFET Halogen Free part switches on allowing reverse current flow. The detectors output 5-15V Vcc range 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.
