NE2280 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.
NE2280 minimizes the number of external components and drastically simplifies the PFC implementation. It also integrates high safety protection features that make the NE2280 a driver for robust and compact PFC stages like an effective input power runaway clamping circuitry. NE2280 permanently monitors the output voltage, the coil current and the die temperature to protect the system from possible over−stresses.
NE2280 offers comprehensive protection coverage UVLO, Soft Start, Over−Power Limitation, Overvoltage protection, coil current limitation, Brown−Out Detection, Over−Power Limitation, thermal shutdown.
NE2280 is offered in SOP-8 package.
