General Description
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 converter system.

Features and Benefits
 • 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

Applications
PFC circuit up to 200 W of output power such as:
 • AC/DC power supply
 • Digital appliances (large size LCD television and so forth).
 • OA equipment (Computer, Server, Monitor, and so forth).
 • Communication facilities
