CS51022A: Enhanced Current Mode PWM Controller for Forward or Flyback (36-72 V Telecom)
The CS51021/22/23/24 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 start-up current (75uA) and high frequency operation capability, the CS51021/22/23/24 family includes over-voltage and under-voltage monitoring, externally programmable dual threshold over-current protection, current sense leading edge blanking, current slope compensation, accurate duty cycle control and an externally available 5V reference. The CS51021 and CS51023 feature bidirectional synchronization capability, while the CS51022 and CS51024 offer a sleep mode with 100uA maximum IC current consumption. The CS51021/22/23/24 family is available in a 16 lead narrow body SO package.
