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.
