MC33368 High Voltage GreenLine Power Factor Controller

MC33368 High Voltage GreenLinet Power Factor Controller The MC33368 is an active power factor controller that functions as a boost preconverter in off line power supply applications. MC33368 is optimized for low power, high density power supplies requiring a minimum board area, reduced component count and low power dissipation. The narrow body SOIC package provides a small footprint. Integration of the high voltage startup saves approximately 0.7 W of power compared to resistor bootstrap.

MC33368 Features

* a watchdog timer to initiate output switching, a one quadrant multiplier to force the line current to follow the instantaneous line voltage a zero current detector to ensure critical conduction operation, a transconductance error amplifier, a current sensing comparator, a 5.0 V reference, an undervo
