Description
FA5501P is a control IC for a power factor correction converter using critical conduction mode of operation. This IC uses a CMOS device with high dielectric strength (30V) to implement low power consumption. It contains a compensated current sense comparator for light load and open/short protection at the feedback (FB) pin. The compensated current sense comparator for light load keeps the output voltage constant from no-load to full-load, while the open/short protection at the FB pin stops output pulses when the voltage divider to detect the output voltage becomes faulty.
