MC33368 Datasheet (ON Semiconductor) - High Voltage GreenLine Power Factor Controller

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
