Enhanced Current Mode  
PWM Controller  
The CS51021A/2A/3A/4A Fixed Frequency PWM Current Mode  
Controller family provides all necessary features required for AC−DC  
or DC−DC primary side control. Several features are included  
eliminating the additional components needed to implement them  
externally. In addition to low startup current (75 mA) and high  
frequency operation capability, the CS51021A/2A/3A/4A family  
includes overvoltage and undervoltage monitoring, externally  
programmable dual threshold overcurrent protection, current sense  
leading edge blanking, current slope compensation, accurate duty cycle  
control and an externally available 5.0 V reference. The CS51021A  
and CS51023A feature bidirectional synchronization capability, while  
the CS51022A and CS51024A offer a sleep mode with 100 mA  
maximum IC current consumption. The CS51021A/2A/3A/4A family  
is available in a 16 lead narrow body SOIC package.
