SSC2005SC is a Critical Conduction Mode (CRM) control IC for power factor correction (PFC). Since no input voltage sensing and no auxiliary winding for inductor current detection are required, the IC allows the realization of low standby power and the low number of external components. The product achieves high cost-performance and high efficiency PFC conver.
Inductor Current Detection (No auxiliary winding required)
Low Standby Power (No input voltage sensing required)
Minimum Off-time Limitation Function to restrict the Rise of Operation Frequency
High Accuracy Overcurrent detection: −0.60 V ± 5 %
Protections
Overcurrent Protection (OCP): Pulse-by-pulse Overvoltage Protection (OVP): Auto restart FB Pin Undervoltage Protection (FB_UVP): Auto restart Thermal Shutdown Protection with hysteresis (TSD): Auto restart
