CS51022A - PWM Controller

Download the CS51022A datasheet PDF. This datasheet also covers the CS51021A variant, as both devices belong to the same pwm controller family and are provided as variant models within a single manufacturer datasheet.

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 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 availabl.

Enhanced Current Mode PWM Controller CS51021A The CS51021A Fixed Frequency PWM Current Mode Controller 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 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 features bidirectional synchronization capability. The CS51021A is available in a 16 lead narrow body SOIC package.
