Enhanced Current Mode
PWM Controller
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 start−up current (75 μA) 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 μA
maximum IC current consumption. The CS51021A/2A/3A/4A family
is available in a 16 lead narrow body SOIC package.
