SC3654 is a controller for Continuous Conduction Mode (CCM) Power Factor Correction step.
up pre.
converters. It controls the power switch conduction time (PWM) in a fixed frequency mode and in dependence on the instantaneous coil current. SC3654 minimizes the number of external components and drastically simplifies the PFC implementation. It also integrates high safety protection features that make the SC3654 a driver for robust and compact PFC stages like an effective input powe.
