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.
