CM6503/4 8-PIN SINGLE PFC CONTROLLER WITH 50% PWM CLOCK SIGNAL GENERAL DESCRIPTION FEATURES The 8 pin single PFC controller with 50% PWM clock , CM6503/4 is a space-saving controller for power factor corrected, switched mode power supplies that offers very low start-up and operating currents.
For the power supply less than 500Watt, its performance could be very close to CM6800 or ML4800 architecture.
Its IAC has dual function.
8 pin CM6503/4 does not require and bleed resistors.
It use IAC pin during the start up condition to start up CM6503/4.
After CM6503/4 is on, IAC will switch itself back to the IAC function.
Power Factor Correction (PFC) offers the use of smaller, lower cost bulk ca...
