NCP1294: PWM Controller for Flyback or Forward Converters

具体说明: The NCP1294 fixed frequency flyback PWM controller...
  • The NCP1294 fixed frequency flyback PWM controller contains all of the features necessary for basic flyback, forward or boost operation. This PWM controller has been optimized for high frequency primary side control operation. In addition, this device includes such features as: Soft Start, accurate duty cycle limit control, less than 50uA startup current, over and under voltage protection, and bidirectional synchronization. The NCP1294 is available in a SOIC-16 and TSSOP-16 surface mount packages.
