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)
