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 bootstrapped circuits.
