1 / 19 page  Critical Conduction Mode PFC Control IC SSC2005SC SSC2005SC-DS Rev.1.1 SANKEN ELECTRIC CO.,LTD. 1 Feb. 06, 2015 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 Typical Application Circuit VAC C1 BR1 L1 C2 RVS2 VOUT VCC OUT COMP FB RDLY GND CS 8 7 6 5 SSC2005SC U1 1 2 4 3 RT CS CP RS Cｆ External power supply RRT RDLY C3 C4 C5 C6 Q1 D1 DBYP D2 DZCS R2 R1 R3 RCS R4 LINE GND RVS1 TC_SSC2005SC_1_R2 Package SOIC8 Not to scale Electrical Characteristics VCC Pin Absolute Maximum Ratings, V CC = 28 V OUT Pin Source Current, I OUT(SRC) = −500 mA OUT Pin Sink Current, I OUT(SNK) = 1000 mA 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).
