The CS51021A/2A/3A/4A Fixed Frequency PWM Current ModeController family provides all necessary features required for AC−DCor DC−DC primary side control. Several features are includedeliminaTIng the addiTIonal components needed to implement themexternally. In addiTIon to low startup current (75 A) and highfrequency operaTIon capability, the CS51021A/2A/3A/4A familyincludes overvoltage and undervoltage monitoring, externallyprogrammable dual threshold overcurrent protection, current senseleading edge blanking, current slope compensation, accurate duty cyclecontrol and an externally available 5.0 V reference. The CS51021Aand CS51023A feature bidirectional synchronization capability, whilethe CS51022A and CS51024A offer a sleep mode with 100 Amaximum IC current consumption. The CS51021A/2A/3A/4A familyis available in a 16 lead narrow body SOIC package.
