NCP1654BD65R2G Datasheet

Power Factor Correction ICs


The NCP1654BD65R2G is a controller for Continuous Conduction Mode (CCM) Power Factor Correction step&minus;up pre&minus;converters. It controls the power switch conduction time (PWM) in a fixed frequency mode and in dependence on the instantaneous coil current.Housed in a SO8 package, the circuit minimizes the number of external components and drastically simplifies the PFC implementation. It also integrates high safety protection features that make the NCP1654BD65R2G a driver for robust and compact PFC stages like an effective input power runaway clamping circuitry. NCP1654BD65R2G Features &bull; IEC61000&minus;3&minus;2 Compliant&bull; Average Current Continuous Conduction Mode&bull; Fast Transient Response&bull; Very Few External Components&bull; Very Low Startup Currents (<75 A)&bull; Very Low Shutdown Currents (< 400 A)&bull; Low Operating Consumption&bull; &plusmn;1.5 A Totem Pole Gate Drive&bull; Accurate Fully Integrated 65/133/200 kHz Oscillator&bull; Latching PWM for cycle&minus;by&minus;cycle Duty&minus;Cycle Control&bull; Internally Trimmed Internal Reference&bull; Undervoltage Lockout with Hysteresis&bull; Soft&minus;Start for Smoothly Startup Operation&bull; Shutdown Function&bull; Pin to Pin Compatible with Industry Standard&bull; This is a Pb&minus;Free Device
