Product Summary

The FA5501A is a FUJI power supply control IC for a power factor correction converter using critical conduction mode of operation. The device uses a CMOS device with high dielectric strength(30V) to implement low power consumption. The FA5501A contains compensated current sense comparator for light load and open/short protection at feedback(FB)pin. Compensated current sense comparator for light load keeps output voltage constant from on-load to full-load.
