The MC33368DG is a high voltage GreenLine 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. It features a watchdog timer to initiate output switching, an 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 5V reference, an undervoltage lockout (UVLO) circuit which monitors the VCC supply voltage and a CMOS driver for driving MOSFETs. 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.
● Lossless off-line startup
● Output overvoltage comparator
● Leading edge blanking (LEB) for noise immunity
● Watchdog timer to initiate switching
● Restart delay timer
