MOSDESIGN SEMICONDUCTOR CORP. POWER FACTOR CORRECTION CONTROLLER POWER M8128A GENERAL DESCRIPTION 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 brownouts. An innovative multi-vector error amplifier is built in to provide rapid transient response and precise output voltage clamping. A built in circuit will disable the controller if the output feedback loop is opened.
