SD7530STR - HIGH POWER FACTOR FLYBACK PWM CONTROLLER

Download the SD7530STR datasheet PDF. This datasheet also covers the SD7530 variant, as both devices belong to the same high power factor flyback pwm controller family and are provided as variant models within a single manufacturer datasheet.

General Description

LED lighting applications.

Key Features

  • a high performance analog multiplier for power factor correction (PFC), zero current detector (ZCD) to ensure TM operation. It integrates a current sensing comparator with built-in leading-edge blanking, and a totem-pole output stage capable of -600mA /800mA current suited for big MOSFET. SD7530 has a built-in soft-start circuit to avoid the over voltage output under light load start, reduce MOSFET’s voltage stress, and improve circuit’s reliability. SD7530 has a built-in output short-ci.
