SC3654 - Boost Power Factor Correction Controller

Download the SC3654 datasheet PDF. This datasheet also covers the SC3654-Safety variant, as both devices belong to the same boost power factor correction controller family and are provided as variant models within a single manufacturer datasheet.

Key Features

  • 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.

SC3654 Continuous Conduction Mode (CCM), Boost Power Factor Correction (PFC) Controller Description Features 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 power runaway clamping circuitry. SC3654 permanently monitors the output voltage, the coil current and the die temperature to protect the system from possible over−stresses.
