L4984D - CCM PFC controller

STMicroelectronics

Datasheet Details

. . . . .

Line-modulated fixed-off-time (LM-FOT) control of CCM-operated PFC pre-regulators.
Proprietary LM-FOT modulator for nearly fixedfrequency operation.
Proprietary multiplier design for minimum THD of AC input current.
Fast “bi-directional” input voltage feedforward (1/V2 correction).
Accurate adjustable output overvoltage protection.
Protection against feedback loop failure (latched shutdown).
Inductor saturation protection.
