SD7530_Datasheet HIGH POWER FACTOR FLYBACK PWM CONTROLLER DESCRIPTION SD7530 is a high power factor flyback PWM controller special for LED lighting applications. SD7530 Features a high performance analog multiplier for power factor correction (PFC), zero current detector (ZCD) to ensure TM operation. It integrates a current sensing parator with built-in leading-edge blanking, and a totem-pole output stage capable of -600m A /800m A 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-circuit protection circuit, in this way the current of the system is considerably reduced to avoid the APPLICATIONS damage to IC. SD7530 includes VCC under voltage lockout, VCC over voltage - LED Daylight lamp protection, and over temperature protection, etc. Features - Transition Mode (TM) operation - High-performance analog multiplier - Built-in restart timer - Integrate digital LEB - Low start-up current (5μA) - Audio noise free - Built-in soft start circuit - Very low power dissipation of output short-circuit protection (SCP) - VCC under vltage lockout with hysteresis (UVLO) - VCC over-voltage protection (VCCOVP) - Over temperature protection (OTP) ORDERING INFORMATION Part No. SD7530S SD7530STR Package SOP-8-225-1.27 SOP-8-225-1.27 Marking SD7530S SD7530S Material Halogen free Halogen free Packing...
