      TRANSITION-MODE PFC CONTROLLER

      SD7528 is a high performance transition-mode power factor correction (PFC) controller.

      SD7528 includes a highly linear multiplier, able to reduce AC input current distortion.

      The output voltage is controlled by means of a voltage-mode error amplifier and a precise internal voltage reference.

      The device features very low consumption with current maximum 15μA before start-up and less than 5.5mA during working.

      SD7528 includes a disable function suitable for IC remote ON/OFF.

      An effective two-step OVP enables to safely handle over-voltage either occurring at start-up or resulting from load disconnection.
