SD7530

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 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-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 Pac...
