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.

MARKING

DIAGRAMS

The 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 undervoltage lockout

(UVLO) circuit which monitors the V supply voltage and a CMOS

driver for driving MOSFETs. The MC33368 also includes a

programmable output switching frequency clamp. Protection features

include an output overvoltage comparator to minimize overshoot, a

restart delay timer and cycle−by−cycle current limiting.
