Product Summary
The MC33368DR2G is an active power factor controller that functions as a boost preconverter in off line power supply applications. 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. The MC33368DR2G is optimized for low power, high density power supplies requiring a minimum board area, reduced component count and low power dissipation.
