Advance Information
High Voltage GreenLine
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.
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 VCC
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.
