SSC2005S
Package：SOIC8
SSC2005S 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.
