GENERAL DESCRIPTION
CM6903B
Low Pin Count PFC/PWM CONTROLLER COMBO
FEATURES
The CM6903B is a space-saving PFC-PWM controller for Patent Number #5,565,761, #5,747,977, #5,742,151,
power factor corrected, switched mode power supplies that
#5,804,950, #5,798,635
offers very low start-up and operating currents. For the Pin to pin compatible with FAN6903/4
power supply less than 500Watt, its input current shaping Enable lowest BOM for power supply with PFC
PFC performance could be very close to CM6800 or Internally synchronized PFC and PWM in one IC
ML4800 architecture.
