Product Summary

The FAN4803CP1 is a space-saving controller for power factor corrected, switched mode power supplies that offers very low start-up and operating currents. 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 FAN4803CP1 includes circuits for the implementation of a leading edge, average current boost type PFC and a trailing edge, PWM.
