Product Description

The NCP1654BD65R2G is a Power Factor 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. The circuit minimizes the number of external components and drastically simplifies the PFC implementation. It also integrates high safety protection features that make the NCP1654 a driver for robust and compact PFC stages like an effective input power runaway clamping circuitry.
Average current continuous conduction mode
Fast transient response
Very few external components
Very low startup currents (<400A)
Low operating consumption
Latching PWM for cycle-by-cycle duty-cycle control
Internally trimmed internal reference
Undervoltage lockout with hysteresis
Soft-start for smoothly startup operation
Shutdown function
Pin to pin compatible with industry standard inrush currents detection
Overvoltage protection
Undervoltage detection for open loop detection or shutdown
Brown-out detection
Soft-start
Accurate overcurrent limitation
Overpower limitation
