M8128A POWER FACTOR CORRECTION CONTROLLER

The M8128A provides simple and high performance active power factor correction. The M8128A provides a controlled on-time to regulate the output DC voltage and achieve natural power factor correction. The maximum on-time of the external switch is programmable to ensure safe operation during AC browno.
