Overview

CM6903A Low Pin Count PFC/PWM CONTROLLER COMBO GENERAL DESCRIPTION FEATURES The CM6903A is a space-saving PFC-PWM 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 input current shaping PFC performance could be very close to CM6800 or ML4800 architecture.
Power Factor Correction (PFC) offers the use of smaller, lower cost bulk capacitors, reduces power line loading and stress on the switching FETs, and results in a power supply fully compliant to IEC1000-3-2 specifications.
The CM6903A includes circuits for the implementation of a leading edge, input c...
