Description

The NCP1654BD133R2G is a PFC (Power Factor Correction) controller for Continuous Conduction Mode (CCM) step-up pre-converters. This electronic component controls the power switch conduction time (PWM) in a fixed frequency mode and depending on the instantaneous coil current. It comes in a SO8 package, which simplifies the PFC implementation and minimizes the number of external components. Additionally, it integrates various high safety protection features, making it an efficient driver for robust and compact PFC stages like an effective input power runaway clamping circuitry.
