NCP1294 Datasheet | onsemi

Flyback, Boost, Forward PWM Controller The NCP1294 fixed frequency feed forward voltage mode PWM controller contains all of the Features necessary to be configured in a Flyback, Boost or Forward topology. 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 50m A startup current, over and undervoltage protection, and bidirectional synchronization. The NCP1294 is available in a 16 lead SOIC narrow surface mount package.
