Safety-Chip SC3654
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. 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.| Part No. | SC3654 |
