DESCRIPTION
FA5500A/FA5501A are control ICs for a power factor correction converter using critical conduction mode of operation. Compensated current sense comparator for light load keeps output voltage constant from no-load to full-load. Open/short protection at FB pin stops output pulses when voltage divider to detect output voltage becomes fault.
