SSC2016S

Critical Conduction Mode PFC Control IC SSC2016S Data Sheet Description SSC2016S is a Critical Conduction Mode (CRM) control IC for power factor correction (PFC). Since no input voltage sensing is 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.
